Best Fluke 1000 Amp Clamp Meter

As an Amazon Associate, this site earns from qualifying purchases. Every current range, count, battery detail, weight and feature in this guide comes from the Amazon product listing and seller copy for each item, and none of it has been checked independently. Where two fields in a listing disagree, the figure is marked Not confirmed and kept out of the comparison.

Start with the most important point. None of the 12 listings is a Fluke 1000 amp clamp meter. The only listing that states 1000 A is an Aicevoos Inrush clamp meter, which is not a Fluke product. The data also includes a Fluke i400s 400 A current clamp probe, which needs a separate meter. This guide compares what the data covers.

A clamp meter measures current without breaking the circuit, by opening its jaws around one conductor. The main differences are current range, AC or AC and DC reading, display count, battery setup and true RMS.

Quick answer by situation

If you need the short version, start here.

• You need a clamp that reads up to 1000 A: Only the Aicevoos (Inrush) listing states 1000 A. It is not a Fluke product, and it lists DC current as well.
• You need a Fluke-branded current clamp: The Fluke i400s is a 400 A AC current clamp probe with a BNC connector. It is not a complete meter, and the listing does not name a compatible meter.
• You need AC and DC current: The Temirup, Proster, FNIRSI and Aicevoos listings all describe AC and DC current measurement. The AstroAI and Klein listings do not.
• You need a low-current or leakage reading: The EITAI listing gives a 10 uA resolution and a 0.00 mA to 300 A range. It is built for leakage current, not heavy loads.
• You want a storage case or test leads for a Fluke meter you already own: The Lebakort case lists Fluke 302, 303, 305, 323, 324 and 325 models, and the Young Dance test lead set is listed as compatible with Fluke.
• You want a simple AC clamp for everyday work: The Klein CL120 measures AC current and non-contact voltage through the clamp, and it includes three AAA batteries.

How to choose: what you need the meter to measure

Start with the work you do most often. If you mostly test branch circuits, motor loads or appliance cords, a range up to 400 A covers most of that, and the AstroAI, ANENG, Klein and Fluke i400s are all in that band. If you work on heavier feeders or service entrances, look at the 600 A and 1000 A listings. The Temirup, Neoteck and FNIRSI go to 600 A, the Proster title gives 800 A, and the Aicevoos goes to 1000 A. Choose a range above the largest current you expect to measure, and check that the listed safety rating matches your work.

Next, decide whether you need DC current. The AstroAI listing says plainly that the CM2K0R cannot test DC current. The ANENG listing states that DC current is none. The Klein CL120 measures AC current through the clamp. The Temirup, Proster, FNIRSI and Aicevoos listings all describe AC and DC current measurement. If you work on battery systems or vehicle electrical loads, DC support is the first thing to confirm. The FNIRSI listing adds that voltage must be measured with the test leads, not the clamp jaws.

Think about the wire size. The jaw opening decides which conductors fit around the clamp. The EITAI has a 40 mm jaw (about 1.6 inches), the Neoteck has a 25 mm jaw, and the Proster has a 28 mm jaw. The Klein listing does not state a jaw size. Measure the largest cable you plan to clamp before you order.

Check whether the meter reads true RMS. The Temirup, Proster, FNIRSI, Aicevoos and Neoteck listings all state TRMS or True RMS. The Temirup listing says true RMS gives accurate readings on non-linear loads. The AstroAI, ANENG, Klein and EITAI listings do not state true RMS.

Finally, look at the low end. Most listings here focus on higher currents. The EITAI gives a 10 uA resolution and a range from 0.00 mA to 300 A, which suits leakage and low-current work. The Neoteck adds a 1 A low-current mode for small circuits. If you need to see very small currents, those two listings are the starting point.

Safety ratings and what they mean

Safety ratings are listed in the specification fields, and they matter for the work you do. CAT III 600 V appears on the AstroAI, EITAI and Neoteck listings. The Temirup lists CAT III 600 V, CAT IV 600 V and CAT III 1000 V. The Fluke i400s lists CAT IV 600 V and CAT III 1000 V. The Proster lists UL 61010-1 and IEC 61010-2-030, and the FNIRSI lists UL 61010-1 and CE marking. The Aicevoos listing does not state a rating.

A rating is only useful if it matches the place you work. Check the category and voltage on the listing and make sure they cover the circuit you are testing. A rating on the meter does not replace careful procedures or the training that electrical work requires.

Where the listings conflict

Several listings disagree with themselves. These are the items to check before you rely on a figure.

• AstroAI: The weight is 415 g in the item weight field and about 203 g in the specification bullets. The storage temperature is given as 14 to 122 F in one place and -10 to 6 C in another.
• EITAI: The item dimensions field reads 70.87 inches long, while the meter size bullet gives 180 by 72 by 32 mm, which is about 7.1 inches long. Those two cannot both be right, so the length is Not confirmed.
• ANENG: The item weight field reads 0.6 g, while the weight bullet reads 129 g. The field figure is clearly wrong, so the 129 g figure is used in the comparison table, marked Not confirmed.
• FNIRSI: The title and the unit count field give 9999 counts, while the style field says 10000 counts. The count is Not confirmed.
• Proster: The title says 800 A, and the style name says voltage tester. The included components field lists only the clamp meter, but the bullets describe test leads, alligator clips and a pouch.
• Temirup: The model field reads CM83E-Red, while the part number field reads MESTEK. The part number and brand do not match.
• Aicevoos: The title says Inrush, while the brand is Aicevoos.
• Fluke i400s: The item type field reads Tester, but the product is a clamp-on probe that needs a separate meter. The title says 400 A, and no compatible meter is named.

Product-by-product breakdown

Each entry below is built from the listed fields and description. Where data is incomplete or inconsistent, the entry says so.

AstroAI CM2K0R Digital Clamp Meter, 2000 Counts

This is a 2000 count clamp meter with AC current up to 400 A, AC and DC voltage, AC current, resistance, capacitance, continuity, live wire testing and non-contact voltage. It runs on two 1.5 V AAA batteries, which are included. The LCD is backlit, the listing describes a flashlight, and auto shut-off is listed.

The listing is clear that this meter cannot test DC current. The clamp must surround one conductor, not the whole power cord, and the conductor should sit in the centre of the clamp head. The weight is Not confirmed: the item weight field reads 415 g, while the specification bullets read about 203 g. The warranty is not stated in the listing. The safety rating is CAT III 600 V with pollution degree 2.

This suits a homeowner or light-duty technician who needs AC current, voltage and continuity, and does not need DC current.

EITAI6540 High Accuracy Leakage Clamp Meter, 300 A

This is a leakage and low-current clamp meter with a range from 0.00 mA to 300 A and a resolution of 10 uA. The jaw opening is 40 mm (about 1.6 inches), and the meter stores up to 99 readings. Functions include peak hold, data hold, overflow display and auto shut-off after five minutes of inactivity.

The power supply is two AAA alkaline batteries, and the listing states that the batteries are not included because of import regulations. Budget for them. The meter weighs 200 g alone and 310 g with its accessories. The item dimensions field reads 70.87 inches, which conflicts with the meter size bullet of 180 by 72 by 32 mm, so the length is Not confirmed. The warranty is not stated in the listing, though the included components list a warranty card.

This is a good fit for leakage or low-current work where a small reading matters more than a very high current range. It is not the right choice for heavy-load current measurement above 300 A.

Temirup CM83E True RMS Clamp Meter, 6000 Counts, 600 A

This is a true RMS clamp meter with a maximum AC and DC current of 600 A, a display of 6000 counts and a temperature range from -20 to 1000 C. It measures AC and DC voltage, resistance, capacitance, continuity and diodes. It includes a non-contact voltage detector with sound and light alarm, a backlit screen and an LED flashlight.

The included components field lists a clamp meter, batteries, test leads and a K probe. The warranty is two years from the manufacturer. The weight is 10.4 ounces. The model and part number fields disagree, with CM83E-Red in one place and MESTEK in another, so confirm the exact model and seller before you buy.

This is a good match for a user who needs both AC and DC current in one meter, plus temperature readings. The safety ratings include CAT III 600 V, CAT IV 600 V and CAT III 1000 V.

ANENG Digital Clamp Meter, 4000 Count

This is a 4000 count clamp meter with AC current up to 400 A, AC and DC voltage up to 600 V, resistance, capacitance, continuity, diode and frequency measurement. The DC current entry reads none, so this meter reads AC current only. It has a backlit screen, a data hold function, a buzzer and an NCV function. The package includes two AAA batteries and a combination lead set.

The weight is Not confirmed: the field reads 0.6 g, which is clearly wrong, and the bullet reads 129 g. The comparison uses the bullet figure with that note. The listing says to press REL to zero the meter before clamping. It names no true RMS, and the warranty is not stated in the listing.

This is a basic AC clamp for everyday troubleshooting. It does not measure DC current, so do not choose it for battery or vehicle loads.

Neoteck MY2610C Clamp Meter, 4000 Count, 600 A

This is an auto-ranging TRMS clamp meter that measures AC current up to 600 A, AC and DC voltage up to 600 V, resistance, diode, continuity and temperature. It has a 1 A low-current mode, a 25 mm clamp jaw and NCV detection from 90 to 1000 V AC. It has a backlit LCD, a flashlight and a low-battery indicator.

The package includes three AAA batteries, a K-type probe, test leads, a manual and a pouch. The weight is 195 g. The warranty is 18 months. The safety rating is CAT III 600 V. The listing includes several useful notices: clamp only one wire, centre the wire in the jaw, close the clamp fully, and choose the range before you measure. Those are worth following on any clamp meter.

This is a solid option for an electrician or homeowner who wants true RMS and a low-current mode in one meter.

Klein Tools CL120 Digital Clamp Meter, 400 A AC

This is an auto-ranging clamp meter that measures AC current up to 400 A through the clamp, and non-contact voltage through the clamp jaw. AC and DC voltage, resistance and continuity are measured through the test leads. The display is backlit, with max and data hold functions and an auto power-off after 10 minutes. The meter includes a test lead holder and an optional magnetic hanger.

The package includes a carrying case, test leads with CAT III and CAT IV safety caps, instructions and three AAA batteries. The item weighs 9.76 ounces, and the dimensions are 8.45 by 3.51 by 1.51 inches. The warranty field reads See Manufacturer Website, which does not give a term, so the warranty is Not stated in the listing.

Because the clamp reads AC current only, do not choose this meter for DC work. It is a good match for a user who wants a well-known brand with a clear accessory package.

Proster PDM-6000NCV Clamp Meter, 6000 Count

This is a TRMS clamp meter with AC and DC current, AC and DC voltage, resistance, capacitance, frequency, diode and temperature measurement. The title gives an 800 A maximum, and the jaw opening is 28 mm. It has a non-contact AC voltage detector that alerts for 90 to 1000 V AC, a continuity buzzer below 50 ohms and a K-type thermocouple for temperature.

The style name reads Voltage Tester, while the measurement type is Multimeter, so the category label is inconsistent. The included components field lists only the clamp meter, but the bullets describe test leads, alligator clips and a zippered pouch. Confirm the contents before you order. The weight is 0.37 kg, and the warranty is not stated in the listing.

This suits a user who wants AC and DC current, a 28 mm jaw and a backlit display. The included accessories are Not confirmed, so ask the seller what is in the box.

Fluke i400s 400 A AC Current Clamp Probe with BNC Connector

This is an AC current clamp probe, not a complete meter. It is rated for 400 A, is hand powered, and includes one clamp-on probe. The listing states a Cat IV 600 V and Cat III 1000 V rating, a one year warranty and a weight of 480 g. The item dimensions are 12.83 by 6.97 by 2.17 inches.

The title says the probe has a BNC connector, and it is a current probe that is read through a separate meter. The listing does not name a compatible meter, so confirm what it connects to before buying. The item type field reads Tester, which does not match a probe. Several UPC codes are listed, which is unusual for a single item. Most of the description is general company text, with few product details.

This is the only Fluke item in the data that measures current, and it reaches 400 A, not 1000 A. It suits a Fluke user who already owns a meter that accepts this probe.

It has a built-in 1500 mAh battery that charges through a Type-C cable.

The count is Not confirmed: the title and the unit count field say 9999, while the style field says 10000. The clamp jaws measure current only, so voltage must be measured with the test leads. The package includes the clamp meter, two multimeter pens, a temperature probe and a Type-C charging cable. The listing gives no warranty term.

This suits a technician who needs to watch intermittent faults over time, or an automotive user who wants DC current in a rechargeable meter.

Young Dance 24-Piece Multimeter Test Lead Set

This is a set of test leads and probes, not a meter. It includes 24 pieces with silicone insulation, banana plugs, alligator clips, test hooks, back probes and piercing probes. The leads are rated 1000 V, 10 A and CAT III. The set is described as compatible with multimeters and test instruments, and the listing names Fluke, KAIWEETS and INNOVA as examples.

The compatibility is a seller claim, so check the connector size on your meter before you buy. The kit includes two 100 cm banana plug leads and two 70 cm leads with test hooks, along with extension probes and connecting bananas. The weight and warranty are not stated in the listing.

This is a good match for a user who needs spare or extra leads for a meter they already own, including a Fluke meter.

Lebakort Hard Case for Fluke 302, 303, 305, 323, 324 and 325

This is a hard protective case with a nylon and hard EVA shell, made to hold Fluke clamp meters in the 302, 303, 305, 323, 324 and 325 models. The inner top has a mesh pocket for accessories, and the lower cover holds the meter in place. The part number is B117 and the colour is black. The listing contains no meter, so buy one separately.

The listing says the case protects against crushing, scratches and water damage. It is a fit only for the models named. The model list repeats with a small typo in one place, which does not change the fit. No warranty period appears in the listing.

This suits a Fluke owner who wants to protect a meter in a bag or on a site. Check your model number against the list before you buy.

View on Amazon

Aicevoos Inrush Digital Clamp Meter, 1000 A TRMS, 6000 Counts

This is the only listing in the data with a 1000 A AC and DC current range. It also measures voltage up to 1000 V DC and 750 V AC, capacitance, frequency, duty cycle, resistance, diodes, continuity and temperature. The surge current function takes about 100 milliseconds, and the listing says it helps identify start-up issues with motors and start-up circuits. It also offers variable frequency drive mode and low impedance voltage mode.

The brand is Aicevoos, while the title says Inrush. That mismatch does not change the specifications, but check the seller before you order. The power source is battery, but the battery type and count are not stated in the listing. The weight, warranty and safety rating are not stated in the listing.

This is the choice for the 1000 A figure in the title, but it is not a Fluke product. It suits a user who needs a wide current range, DC support and VFD mode in one meter.

Who should buy, who should skip

Buy one of these items if:

• You need AC and DC current in one meter. The Temirup, Proster, FNIRSI and Aicevoos listings all describe AC and DC current.
• You need a current range above 400 A. Temirup, Neoteck and FNIRSI list 600 A, Proster’s title gives 800 A, and Aicevoos lists 1000 A.
• You need a low-current or leakage reading. The EITAI and the Neoteck low-current mode are the starting points.
• You already own a Fluke meter that accepts a current probe. The Fluke i400s is the only Fluke current item in the data.
• You want a storage case or spare leads for a Fluke meter. The Lebakort case and the Young Dance lead set both list Fluke compatibility.
• You want a simple AC clamp with a known brand and a clear accessory package. The Klein CL120 is the best fit in this set.

Skip these items if:

• You need a Fluke 1000 A clamp meter. None of the listings is one.
• You need DC current and buy an AC-only meter. The AstroAI, ANENG, Klein and Fluke i400s do not measure DC current.
• You need a warranty term. Most listings do not state one. The Temirup, Neoteck and Fluke i400s listings do state a term, and the Klein field points to the manufacturer’s website without giving one.
• You need a meter that works without buying batteries. The EITAI listing says its batteries are not included.
• You need a complete meter from the Fluke i400s listing. It is a probe, and it needs a separate meter.

Situations where these items fit:

A homeowner checking a branch circuit or appliance cord can use the AstroAI or ANENG. Both read AC current up to 400 A, and both include batteries. The AstroAI listing says to clamp one conductor only, and the ANENG listing says to press REL before clamping.

An electrician working on feeders or service equipment needs a higher range and a safety rating that matches the circuit. The Temirup and Neoteck list CAT III 600 V, and the Temirup also lists CAT IV 600 V.

A technician troubleshooting intermittent faults over time can use the FNIRSI, which records readings and can show curves on screen.

A Fluke owner who already has a meter can add the i400s probe, a case or spare leads. Check the model and connector before buying.

A user who works with leakage or small currents can start with the EITAI, which reads down to 0.00 mA.

Pre-purchase checklist

1. Confirm the current range. Choose a range above the largest current you expect to measure. The listings range from 300 A to 1000 A.
2. Check AC or DC. Several listings are AC only. None of the AstroAI, ANENG, Klein or Fluke i400s models measure DC current.
3. Measure the conductor. Check the jaw opening: 40 mm for EITAI, 28 mm for Proster, 25 mm for Neoteck. The Klein jaw is not stated.
4. Confirm true RMS if you need it. The Temirup, Proster, FNIRSI, Aicevoos and Neoteck list TRMS.
5. Check the safety rating. Match CAT and voltage to the work. The Fluke i400s is rated CAT IV 600 V and CAT III 1000 V.
6. Check what is in the box. The EITAI batteries are not included, and the Proster included components field lists only the clamp meter.
7. Confirm the weight. Where the field and the bullets disagree, as with AstroAI and ANENG, treat the figure as Not confirmed until the seller answers.
8. Check the count. The FNIRSI listing shows 9999 and 10000 counts.
9. Check the compatibility. For the Lebakort case and the Young Dance leads, match the model or connector to your meter.
10. Ask about the warranty. Most listings do not state a term. If the warranty matters, confirm it with the seller before ordering.

Care and safe use from the listings

Several listings give safety notes that apply to every clamp meter. The Neoteck listing says to clamp only one wire, because clamping both the live and neutral wires makes their currents cancel. It says to keep the wire in the centre of the jaw, since an off-centre wire reduces accuracy, and to close the clamp tightly, since dirt or a loose hinge can leave a gap. It also says to choose the range before measuring and to start high if you are unsure.

The AstroAI listing makes the same point about the power cord. Clamp around one conductor, not the whole cord, and keep the conductor in the centre of the clamp head.

The ANENG listing says to press REL to zero the meter before clamping. Do this each time you start a reading.

The FNIRSI listing says voltage must be measured with the test leads, since the clamp jaws measure current only.

The Klein listing includes test leads with CAT III and CAT IV safety caps. Use the caps and check the leads for wear before each job.

The EITAI listing gives a working range of 0 to 40 C with humidity below 80 percent, so keep the meter within those limits.

The Klein listing includes a carrying case, and the Lebakort listing describes a protective case for Fluke meters. Use a case to protect the jaws and display when the meter is not in use.

Common mistakes

Expecting a Fluke 1000 A meter. None of the listings is one. The 1000 A figure in the title belongs to the Aicevoos listing, which is not a Fluke product.

Clamping both wires. The Neoteck listing says the currents cancel out and give a near-zero reading.

Buying an AC-only meter for DC work. DC current is not measured by the AstroAI, ANENG, Klein or Fluke i400s.

Assuming batteries are included. The EITAI listing gives no battery in the box.

Choosing the wrong range. The Neoteck listing warns that a range set too high can make a reading appear very low or inaccurate, and it says never to use a small current range for a larger current. Start high and step down.

Ignoring the probe requirement. The Fluke i400s is a probe, and the listing does not name a compatible meter. Confirm the connection before buying.

Trusting a single weight. The AstroAI and ANENG listings show two different figures.

Skipping the zero step. The ANENG listing says to press REL before clamping.

What the listings cover for high-current clamp meters

No product in this set is listed as a Fluke 1000 amp clamp meter. The one Fluke model in the data is the Fluke i400s, a 400 amp AC current clamp with a BNC connector, and the listing gives its current rating and CAT ratings but few other specifications. If the 1000 amp rating is the reason you are shopping, compare the current ranges with the Aicevoos listing (1000 A), the Proster listing (800 A) and the Temirup listing (600 A).

AC-only and AC/DC clamps behave differently. The AstroAI CM2K0R listing says it cannot test DC current. The ANENG listing says its clamp measures AC current only, while its voltage and resistance functions cover AC and DC. The Temirup and FNIRSI listings state AC and DC current, so check the mode you need before buying.

Jaw size and how the clamp is used

The jaw decides which cables fit. The ANENG listing states that its double-open jaw measures a wire up to 1.42 inches across. The Proster listing gives a 28 mm jaw. The EITAI listing gives a 40 mm jaw, the largest jaw size stated in the listings above, and it is aimed at leakage work at low current.

The listings give the same basic instruction: clamp around one conductor, not the whole cord. The Neoteck listing says the wire should sit in the middle of the jaw. The Neoteck listing warns that clamping both the live and neutral wires makes their currents cancel, so the reading is close to zero. A loose hinge or dirt on the jaw faces can also cause a weak reading.

Current limits to check

• Fluke i400s: rated for 400 amps AC with CAT IV 600 V and CAT III 1000 V listings.
• Temirup CM83E: 600 A AC and DC current, 6000 counts, backlit display.
• Aicevoos: 1000 A AC and DC current, with a surge function that measures in about 100 milliseconds.
• EITAI 6540: 0.00 mA to 300 A, with 10 uA resolution and up to 99 stored groups.
• FNIRSI DMC-100: 600 A AC and DC current, with 8 real-time data sets and 30 historical records.

When the current is well below the top of a range, the reading can look small or unreliable. The Neoteck listing recommends starting on the highest range and stepping down, and warns against using a small range on a large current. The Neoteck listing also notes that the reading is accurate only on a single wire.

Frequently asked questions

Is any listing a Fluke 1000 amp clamp meter?

No. The 1000 A listing in this data is the Aicevoos (Inrush) meter, which is not a Fluke product. The Fluke item in the data is a 400 A current probe.

Which meters measure DC current?

The Temirup, Proster, FNIRSI and Aicevoos listings describe AC and DC current measurement. The AstroAI, ANENG, Klein and Fluke i400s do not.

Which listings include batteries?

The AstroAI, ANENG, Temirup, Neoteck and Klein listings state batteries are included. No battery comes with the EITAI listing. The Proster and Fluke i400s listings do not state battery details.

What does TRMS mean?

TRMS stands for true root mean square. The Temirup, Proster, FNIRSI, Aicevoos and Neoteck listings state it. The Temirup listing says it gives accurate readings on non-linear loads.

Can I use the Fluke i400s on its own?

The listing describes a current probe, not a complete meter. It needs a separate meter, and the listing does not name a compatible one.

Why are some weights marked Not confirmed?

The AstroAI and ANENG listings give two different weights in different fields. Until the seller confirms which is right, the comparison notes the conflict.

Which meter reads the smallest current?

The EITAI reads from 0.00 mA with a 10 uA resolution, so it is the closest match for low-current or leakage work in this data.

What should I check first?

Start with the current range and whether you need AC or DC. Then check the jaw opening, the safety rating and what is included in the box.
