Uni t ut202a digital clamp meter

Digital Clamp Meter Buying Guide: 12 Options Compared

ByKen

Every product detail in this guide comes from the Amazon listing data and seller descriptions supplied for this roundup.

Quick answer: no UT202A listing is in this set

The keyword for this page is UNI-T UT202A, but none of the twelve listings is a UT202A. The only UNI-T listing is a UT210E mini clamp meter. The CTDOFUM and JFVMLAIU listings name UT210 models in their titles, and the JFVMLAIU title names four of them (UT210A, UT210C, UT210D and UT210E). The rest come from other brands, and two of them are not clamp meters in the usual sense. This guide therefore compares the full set on the features that matter for buying a clamp meter, and it does not claim any listing is a UT202A.

If you need a UT202A specifically, search for that model number directly. If you are open to a clamp meter from this set, these are the strongest starting points:

What this roundup covers, and what it does not

Two listings are not general-purpose clamp meters. The Megger DET14C is listed as a clamp-on ground resistance meter for earth testing. The carrying case for the Klein ET310 circuit breaker finder kit is a bag, not a meter. The remaining ten are meters, and they differ in current range, voltage range, the features they list, and how much of the spec sheet they publish.

Because of that mix, this guide separates the two non-meter listings from the meters and explains each one in its own section. Treat the bag as an accessory, and treat the ground resistance meter as a different tool from the others.

How to read clamp meter specs in plain terms

Clamp meter listings use a set of fields. Each one tells you something about what the meter can do and how it will behave in the field.

AC and DC current. A clamp meter measures current by clamping around a conductor rather than connecting leads into the circuit. Several listings state that the meter reads AC current only. The AstroAI says it cannot test DC current, and the ANENG lists DC current as “none.” The Temirup, the BLACK CANYON and the Aicevoos list both AC and DC. If you work on DC circuits, the AC-only listings do not fit that job.

Current range. The current range is the highest current the meter reads, in amps. The set runs from 100A on the UNI-T UT210E to 1000A on the BLACK CANYON and the Aicevoos. A higher range does not make a meter better for small loads, but it does mean the meter covers bigger conductors and higher currents.

Voltage range. Voltage ranges are listed as AC, DC or both. The AstroAI and the ANENG list 600V AC and DC, the BLACK CANYON lists 750V AC and 1000V DC, and the Aicevoos lists 750V AC and 1000V DC. Several listings do not give a voltage ceiling.

True RMS. True RMS (TRMS) is listed on several meters. The Temirup listing describes its true-RMS mode as giving accurate readings on non-linear loads. Several others do not mention TRMS, so do not assume it is present.

Non-contact voltage (NCV). NCV detection lets you check for voltage without touching a wire. Most listings include NCV. The Precalixor lists NCV from 90V to 1000V, and the listings describe it as using a sound and light alarm. NCV is a screening tool and does not replace a separate voltage check.

Counts and resolution. Counts describe the display resolution. A 6000-count display has more digits than a 2000-count display, but the listings do not explain how that changes accuracy. The AstroAI lists 2000 counts, the Temirup 6000, the ANENG 4000, and the Aicevoos and Precalixor 6000.

Data hold, max and min. Data hold freezes a reading on the display. Max and min record the highest and lowest values. Several listings include both, which helps when a reading changes too fast to read.

Auto-ranging and auto power-off. Auto-ranging selects the measurement range for you, which is helpful if you are not sure what range to expect. Auto power-off turns the meter off after a set period. The Temirup and the Klein list auto power-off after 10 minutes of inactivity.

Backlight and flashlight. Backlit screens help when light is poor. The Temirup and the Aicevoos add a flashlight, and the Klein and the BLACK CANYON list backlit screens.

Safety ratings. Safety ratings appear in several specification fields. The AstroAI lists CAT III 600V, the Temirup lists CAT III and CAT IV 600V and CAT III 1000V, the Klein lists CAT III and CAT IV safety caps on its test leads, and the Megger lists CAT IV 600V. These ratings describe the environment the meter is designed for, so read the category on the product page before you use the meter on a high-energy system.

Warranty. The Temirup lists a 2-year manufacturer warranty, the Precalixor lists 1 year, the Klein refers to the manufacturer’s website, and the Megger says no warranty. Most listings state no warranty at all in the supplied data.

Comparison table

The table below puts the core fields side by side. Where a listing does not give a value, the table says so. Where two fields in the same listing disagree, the table says “Not confirmed” and the product section explains why.

Product-by-product breakdown

Each entry covers the meter’s function, the specs that matter most, who it suits and what to check before buying. The order follows the sequence of the supplied listings.

AstroAI Digital Clamp Meter, 2000 Counts, AC Current

The AstroAI is an auto-ranging clamp meter that measures AC current, AC and DC voltage, resistance, capacitance, continuity and live-wire conditions. It cannot test DC current, so it is a fit only for AC work. It has a 2000-count display, which samples three times per second, and an LCD of 35 by 25 millimeters.

The listing includes two 1.5V AAA batteries, a pair of test leads, a user manual and a storage bag. The safety rating is CAT III 600V with pollution degree 2. The item is battery powered, and the listing names a beep for continuity and an OL indicator for overload.

Two numbers conflict. The item weight is listed as 415 grams, and a second weight field gives about 203 grams, so the weight is marked Not confirmed. The storage temperature line also gives 14 to 122 degrees Fahrenheit, which converts to about negative 10 to 50 degrees Celsius, but the same line lists the Celsius range as negative 10 to 6 degrees. The upper storage limit is therefore Not confirmed. Check the product page before you rely on either figure. The dimensions are 195 by 68 by 29 millimeters, which is compact enough for a tool bag.

Temirup Digital Clamp Meter, 6000 Counts, TRMS 600A

The Temirup is a true-RMS clamp meter with a 600A AC and DC current range, a 600V AC and DC voltage range, and a 6000-count display. The listing gives a maximum display value of 5999. It measures temperature from negative 20 to 1000 degrees Celsius, and it covers capacitance and diodes as well.

The meter has a large jaw opening, a backlit screen and an LED flashlight for low-light work such as electrical closets and behind appliances. It includes a zero function for reducing data error, data hold, automatic range, a selection button and auto power-off after 10 minutes of inactivity. The NCV function has a sound and light alarm.

The weight is 10.4 ounces and the item dimensions are 7.8 by 2.9 by 1.3 inches. The included list names the meter, batteries, test leads and a K-probe. The warranty is listed as 2 years from the manufacturer. The safety ratings are CAT III and CAT IV 600V and CAT III 1000V.

ANENG Digital Clamp Meter, 4000 Count, NCV

The ANENG is a 4000-count clamp meter that measures AC current, AC and DC voltage, resistance, capacitance, diodes, continuity and frequency. The DC current field reads “none,” so this meter is for AC current only. The AC current range is 0A to 400A, and the AC voltage range is 0V to 600V, both with a tolerance listed in the specs.

The package includes the meter, two AAA batteries and a combination test lead kit with capacitor and probe accessories, according to the note list. A backlit screen, data retention, a buzzer and NCV sensing.

The weight is listed as 0.6 grams in one field and 129 grams in another, so the weight is marked Not confirmed. A 0.6-gram meter is not plausible, so neither figure should be relied on until you check the product page. The note also says to press REL to zero the meter before clamping, which is a step to follow on each use.

Klein Tools CL120 Digital Clamp Meter, Auto-Ranging 400 Amp AC

The Klein CL120 is an auto-ranging AC clamp meter with a 400A range. It also measures AC and DC voltage, resistance and continuity through test leads, and it has non-contact voltage testing built into the clamp jaw. The listing describes the NCV feature as convenient because it sits in the jaw rather than on a separate probe.

The meter includes a backlit display for low-light conditions, a test lead holder on the side of the clamp, and an optional magnetic hanger (catalog numbers 69445 and 69417). It has max and data hold functions and auto power-off after 10 minutes. 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 measures 8.45 by 3.51 by 1.51 inches. The warranty is listed as “See Manufacturer website,” so check the manufacturer’s terms before you buy. The clamp is described for AC current, and the listing does not state a DC current range.

Megger DET14C Digital Earth Test Clamp-On Ground Resistance Meter

The Megger is a different kind of tool from the other meters here. Its title describes a clamp-on ground resistance meter for earth testing. The listing does not give current or voltage ranges in the way the clamp meters do, so it is not a substitute for a multimeter or a standard clamp meter.

The listing names a large elliptical clamp design, smooth mating surfaces on the clamp head, CAT IV 600V operation, a noise filter function and an intelligent data hold function with time- and date-stamped results. The included components are the unit and an instruction guide.

The weight is 2.2 pounds and the item dimensions are 4.1 by 10.9 by 12.4 inches. The warranty field reads “No Warranty,” so the listing does not offer one. Buy this tool only if your job calls for earth or ground resistance testing, and not as a general clamp meter.

Carrying Case Compatible with Klein ET310 Circuit Breaker Finder and Clamp Meter

This item is a carrying case, not a meter. The title says it fits the Klein ET310 AC circuit breaker finder, GFCI outlet testers and other electrical test kits, and the listing describes two main compartments, two mesh pockets and a front pocket. The case is orange and has a top handle.

The listing describes the upper layer as holding a Klein ET310 circuit breaker finder, an outlet repair tool kit and an RT250 GFCI outlet tester. The lower layer is described for a voltage test kit and several Klein digital multimeter models, and “case only,” so the tools are not included. The shell is soft, and the material is described as scratch-proof and water resistant. The water resistance level field reads “Water Repellent,” which is a different label from the description.

The case measures 10.7 by 4.7 by 8 inches and weighs 0.39 kilograms. Check the fit with your own tools before you buy, because the listing does not give internal compartment dimensions beyond the overall size.

Precalixor Digital Clamp Meter TRMS with Bluetooth App, 6000 Counts

The Precalixor is a TRMS meter with a 6000-count display and Bluetooth app. The title calls it a clamp meter, but the features listed are voltage, resistance, capacitance, frequency, duty cycle, continuity and diode tests, plus NCV detection from 90V to 1000V. The listing does not state a current measurement, so AC and DC current are marked Not stated in the listing.

The app records data over time, shows real-time readings, tracks max, min and average values, and exports reports. It also has a backlit LCD, data hold, max and min, and smart power-off. The listing names dark engine bays and cramped utility closets as places where the backlight helps.

The included list names the manual, two batteries and two test leads. The warranty is 1 year. The weight is 9.76 ounces and the item dimensions are 2.95 by 1.45 by 8.15 inches. Check the product page for the current specification before you buy if you need clamp current.

UNI-T UT210E Mini Digital Clamp Meter, 100A AC DC, True RMS

The UNI-T UT210E is the only UNI-T listing in the set and the closest UNI-T model available here. It is a mini clamp meter with AC and DC current up to 100A, a 1mA resolution on the current range and true RMS measurement. The listing also says it works as a multimeter for AC and DC current and voltage, resistance, capacitance and diodes.

The NCV function uses an electric-field sensor to indicate whether AC voltage is present, and you can choose the sensitivity range. The VFC function is described as reducing the effect of high-frequency signals on readings. The listing describes the meter as small enough to carry in a pocket.

The item weighs 170 grams, and the item dimensions are 2.36 by 6.89 by 1.32 inches. The listing names the UL specification. It does not state a warranty or the included components, so check the product page for those details. The listing does not give a voltage ceiling, so voltage range is marked Not stated in the listing.

BLACK CANYON Digital Clamp Meter, TRMS AC/DC, 1000A

The BLACK CANYON is a TRMS clamp multimeter with a 1000A current range and both AC and DC current. The notes say it measures AC voltage from 6V to 750V and DC voltage from 6V to 1000V, plus resistance, continuity, frequency, duty cycle, DC microamps, diodes, capacitance, inrush current and temperature through a thermocouple. The NCV function detects non-contact voltage.

The notes list data hold, max and min, relative zero measurements, a backlit LCD, a sturdy ABS housing and automatic power-off. The notes also say the kit includes three AAA batteries and a thermocouple. The included-components field lists only the digital clamp meter, so the batteries and thermocouple are marked Not confirmed. Check the box contents on the product page.

The listing gives no weight or dimensions in the supplied data. The specs it does give, including CSA, ETL, CE and IEC 61010-1 marks, are listed in the specification field, but the category rating for each use is not spelled out. Read the product page before using it on a high-energy system.

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

The Aicevoos is a 1000A true-RMS clamp meter with a 6000-count display. It measures AC and DC current up to 1000A, 1000V DC and 750V AC, along with capacitance, frequency, duty cycle, resistance, diodes, continuity and temperature. It has an inrush or surge current function that the listing describes as taking about 100 milliseconds per measurement, and it works on AC current only.

The notes describe a variable frequency drive mode and a low-impedance volts mode, which help measure drive-controlled equipment and eliminate phantom readings. These are seller descriptions, so check the product page for the detailed operating instructions before you use these modes.

The listing includes NCV detection, a backlit LCD, a flashlight, data hold and max and min. The weight, dimensions, warranty and included components are not stated in the supplied data. Check the product page before you buy if you need any of them.

CTDOFUM UT210E and UT210D Digital AC/DC Clamp Meter, True RMS

The CTDOFUM listing covers the UT210E and UT210D models in one title. The notes say it is a mini true-RMS auto-range clamp meter with a 2000-count display, measuring up to 200A on the UT210D and 100A on the UT210E. It measures AC voltage and AC current, and it includes a non-contact voltage function through a sensor on the top of the clamp head.

The listing describes the meter as pocket-sized with an easy grip. The notes say it suits residential, mechanical and electrical equipment maintenance, and home appliance installation. The listing also describes a double-injection rotary knob for selecting functions.

The item weight is 50 grams, which is far below the 170 grams listed for the UT210E in the separate UNI-T listing. The weight is therefore marked Not confirmed. The color field reads “UT210E,” which is a model name, not a color. The listing does not give a warranty, batteries or included components in the supplied data.

JFVMLAIU UT210A and UT210E Mini Clamp Meter, True RMS, Auto Range

The JFVMLAIU is a one-piece mini clamp meter listed with UT210E, UT210D, UT210C and UT210A models in the title. The color field reads “UT210A(Only AC),” which suggests the UT210A model measures AC only. The listing does not state the full specification for the other models, so check the product page before you choose one.

The power source is listed as battery powered and the specification field names the UL mark. The notes say only “Multimeters & Analyzers” and repeat the title, so the listing gives little beyond the model names. Current range, voltage range, NCV, batteries, warranty and weight are not stated in the listing.

This is the thinnest listing in the set. It may suit someone who has confirmed the model on the product page and only needs the basic AC clamp function. It is not a good choice for anyone who needs DC current, a voltage ceiling or a warranty term.

Who should buy and who should skip

The lists below rely only on the facts in the listings.

Good fits:

  • You need AC and DC current in one meter. The Temirup, the BLACK CANYON and the Aicevoos list both.
  • You need a high current range. The BLACK CANYON and the Aicevoos list up to 1000A.
  • You want a warranty term in the listing. The Temirup lists 2 years, and the Precalixor lists 1 year.
  • You want a compact meter for a tool bag. The UNI-T UT210E at 170 grams and the Klein CL120 at 9.76 ounces are the compact choices with clear weight figures.
  • You want data logging to a phone. The Precalixor lists a Bluetooth app that exports reports.
  • You want a meter with included batteries. The Temirup, the Klein, the AstroAI, the ANENG and the Precalixor list batteries in the box.

Skip these unless you check first:

  • You need DC current. The AstroAI and the ANENG say no DC current, and the Klein, the Precalixor, the CTDOFUM and the JFVMLAIU listings do not state a DC current range.
  • You need a UT202A specifically. No listing in this set is one.
  • You need earth or ground resistance testing from a general clamp meter. The Megger is a ground resistance meter, not a general clamp meter.
  • You need a carrying case as a meter. The carrying case is an accessory with no measuring function.
  • You need a known weight or a warranty term. Several listings give no weight or warranty.

Jobs these meters are described for

These uses come from the listing descriptions and notes.

Electrical closets and behind appliances. The Temirup lists low-light use in electrical closets and behind appliances, and the Klein lists a backlit display for low light.

Automotive and engine bays. The Precalixor notes say its backlight helps in dark engine bays.

Residential and HVAC maintenance. The CTDOFUM notes list residential, mechanical and electrical equipment maintenance, and home appliance installation. The UT210E is described as suitable for electricians and HVAC professionals in the CTDOFUM notes.

Motor and startup current checks. The Aicevoos lists inrush or surge current, which it says helps identify startup issues in motors or startup circuits.

Drives and variable frequency equipment. The Aicevoos lists a variable frequency drive mode, and the listing describes it as helping with high-precision readings on those systems.

Earth and ground testing. The Megger is listed for ground resistance testing. Use it only for that purpose.

Safety ratings and what they mean

Several listings give safety categories, and the table below restates them as the listings give them. The categories describe the electrical environments the meters are designed for, and the listing does not explain every use case, so read the full specification on the product page.

  • CAT III 600V: the AstroAI lists this rating with pollution degree 2 and an altitude limit under 2000 meters.
  • CAT III and CAT IV 600V, and CAT III 1000V: the Temirup lists these ratings in its specification field.
  • CAT III and CAT IV safety caps: the Klein lists these on its test leads.
  • CAT IV 600V operation: the Megger lists this rating for installations up to 600V.
  • IEC 61010-1: the Temirup, the Megger and the BLACK CANYON specification fields list this standard.

Do not use any listing’s safety rating as a reason to work on energized equipment without the training and tools that the job requires.

Check before you buy

Work through this list on each product page before you order.

  1. Confirm the model. No listing is a UT202A. If you need that exact model, search by model number and compare the specs with the set.
  2. Confirm AC or DC current. Several listings are AC only or do not state DC current.
  3. Confirm the current range. Check the current range against the conductors you plan to measure.
  4. Confirm the voltage range. Several listings give no voltage ceiling, so check the product page before relying on a meter for high-voltage work.
  5. Confirm the safety category. Read the CAT rating for your work and check that the test leads match it.
  6. Confirm the batteries. Some listings include AAA batteries, and others do not state them. The BLACK CANYON is marked Not confirmed.
  7. Confirm the weight. The AstroAI, the ANENG and the CTDOFUM weights are marked Not confirmed.
  8. Check the warranty. The Temirup lists 2 years, the Precalixor 1 year, the Klein refers to the manufacturer’s website, and the Megger has none.
  9. Check the included parts. The UNI-T UT210E, the Aicevoos and the JFVMLAIU do not list included components in the supplied data.
  10. Match the tool to the job. The Megger is a ground resistance meter, and the carrying case has no measuring function.

Care and storage

The listings give little formal care guidance. The Temirup and the Klein list auto power-off after 10 minutes of inactivity, which helps save battery life. The AstroAI lists a storage temperature range and an operating temperature range, so check both before you store the meter in a hot or cold space. The Klein and the AstroAI include a carrying case or storage bag, and the Carrying Case listing is designed for a Klein circuit breaker finder and related tools.

The Temirup lists a low-battery indication, and the BLACK CANYON lists automatic power-off to conserve battery life. Check each product page for the full care and maintenance guidance, since the supplied data does not include care instructions for every product.

Common mistakes

Assuming the UT202A is in the set. No listing is a UT202A, so a search for that model will not find one here.

Buying an AC-only meter for DC work. The AstroAI cannot test DC current, and the ANENG lists DC current as none.

Trusting a single weight figure. The AstroAI, the ANENG and the CTDOFUM each list conflicting or unlikely weights, so check the product page.

Assuming a clamp meter measures voltage the same way. NCV is a screening function, while voltage and current measurements need the leads or clamp in the right mode.

Ignoring the safety category. Read the CAT rating for your job, not just the voltage figure.

Buying a ground resistance meter by mistake. The Megger is a different tool from a clamp multimeter, and its features do not match a general clamp meter.

UNI-T models and near-copies in this set

The UNI-T UT210E listing describes a mini clamp with a multimeter function. It measures AC and DC current, AC and DC voltage, resistance, capacitance and diodes, and it lists a current resolution of 1 mA on its 100 A range. The listing says it has a non-contact voltage (NCV) test and a VFC function that reduces high-frequency interference. The CTDOFUM listing describes a UT210E and UT210D with a 2000-count display, a 200 A range on the UT210D and a 100 A range on the UT210E.

The JFVMLAIU listing covers the UT210A. Its colour field reads UT210A (AC only), so it is an AC-only clamp. Check the model number on the page before buying, because several listings use the UT210 name for different models.

Carrying cases for clamp meters

The ZIOZERTT case is listed as fitting Klein Tools ET310 circuit-breaker finders and GFCI testers. Its size is 10.7 by 4.7 by 8 inches, and its listing describes two main compartments, two mesh pockets and a front pocket. It is a soft case, not a hard case, and it is water repellent rather than waterproof. Confirm the fit against your own tool before ordering, since the listing is written for the Klein kit.

Specs to compare

  • Current range: UT210E lists 100 A; CTDOFUM lists 200 A on the UT210D.
  • Resolution: the UT210E listing gives 1 mA at its 100 A range, which suits small current checks.
  • Battery: most listings in this set use battery power; the UT210E listing says battery powered but does not name the battery.
  • Weight and size: the UT210E listing gives 170 grams and a 2.36 by 6.89 by 1.32 inch size, which makes it a pocket-sized tool.

When the listing does not state a value, the table marks it as not stated. A missing battery type or unclear model number is a reason to check the live page before buying.
