This roundup compares six handheld digital multimeters whose Amazon listings give a voltage rating, a count or resolution figure, and a list of measurement functions. The Thsinde 18b+ model named in the original title does not appear in the listing set, so this page does not describe it. Every figure below comes from the listing data, with the product record dated 11 October 2026.

Quick answer: for mains work at 240 V, the listings for the Fluke 87V, UNI-T UT161E, Hioki 3244-60 and Neoteck VC746A each state a voltage rating above 240 V. For a voltage rating of 1000 V, choose the Fluke 87V or the UNI-T UT161E. For the smallest body, the Hioki 3244-60 is a card-size meter. For a built-in non-contact voltage (NCV) function, the TESMEN TSM-599, the UNI-T UT161E and the Neoteck VC746A each list NCV.

How we chose these six

The set is a roundup of handheld multimeters, not clamp meters or single-purpose pens. A meter made the list when its listing gave a voltage rating or a count figure, and named its functions in the title or bullets. Listing data checked 11 October 2026 is the only source. Where a figure is missing from the listing, the table says “not stated” rather than an estimate.

  • Voltage rating: the listing states a rating in volts that a reader can check against a circuit.
  • Counts: the listing gives a count, so the display step can be worked out (see the worked example below).
  • Functions: the listing names the functions in the title or bullets, so the reader knows what the meter claims to do.

1. Fluke 87V Industrial Digital Multimeter

The title gives the model as 87V, while the model field reads FLUKE-87-5. The listing states AC and DC voltage up to 1000 V, CAT III 1000 V and CAT IV 600 V safety ratings, and an operating altitude of 2000 m. Its bullets describe a display that switches between 6000 and 20,000 counts, a peak capture that the listing says catches events as short as 250 µs, and a low-pass filter for frequency readings on adjustable speed drives. The listed warranty is 10 years. The package includes TL75 test leads, AC175 alligator clips, a holster and a temperature probe. The listing weight is 1.3 pounds. Check the Fluke 87V on Amazon.

2. Hioki 3244-60 Card HiTester and Digital Multimeter

This is the smallest meter in the set. The listing describes a palm-size body less than 1 cm thick that weighs 0.06 kg. It states 41.99 MΩ resistance and 500 V AC and DC voltage. The Power Source field reads “419.9mv to 500v”, which looks like a voltage span rather than a power source, so we read it that way. The bullets state full auto-ranging, automatic power saving, overload protection to 500 V in the resistance and continuity functions, and gold-plated test lead tips with a pin length of 15 mm. The listing does not state a current range, and this page does not give one. Check the Hioki 3244-60 on Amazon.

3. Innova 3340 Professional Automotive Digital Multimeter

Innova positions the 3340 for engine and automotive work. The bullets list alternator diodes, duty cycle, solenoids, breaker points, wiring and switches. The listing states up to 15 A for device testing, 10 MΩ input impedance, auto-ranging, auto shut-off and overload protection. The warranty is one year, limited. The listing weighs 8 ounces. The listing data conflicts on power: the Power Source field reads “Corded Electric”, but no bullet mentions a cord. Confirm the power source on the unit itself before you plan around it. Check the Innova 3340 on Amazon.

4. UNI-T UT161E Digital Multimeter

The UT161E’s bullets give a 22,000-count display, the highest count figure among the six listings. The listing states AC and DC voltage up to 1000 V, AC and DC current up to 20 A, CAT III 1000 V and CAT IV 600 V ratings, and capacitor, frequency and duty-cycle functions. A bullet describes NCV detection and USB data transmission. The compatibility field lists smartphones running iOS 10.0 and later or Android 5.0 and later, and computers with a Bluetooth adapter, so check which connection you plan to use. The listed weight is 1.5 pounds. Check the UNI-T UT161E on Amazon.

5. TESMEN TSM-599 Smart Digital Multimeter

The title gives TRMS and 6000 counts. The bullets describe two modes. In auto mode the meter switches between DC and AC voltage, resistance and continuity without a range selection. In manual mode it reads DC and AC current, diode, capacitance, Hz%, temperature, NCV and live wire. The listing states a 10 A/250 V fuse, an automatic power-off after 15 minutes, and a color LCD with an analog bar. The certifications are CSA and ETL. The data we hold does not state a voltage range, so the table leaves that cell as “not stated”. Check the TESMEN TSM-599 on Amazon.

6. Neoteck 2000 Counts Digital Multimeter with NCV (VC746A)

The Neoteck meter weighs 195 g according to the listing, which is lighter than the Fluke and the UNI-T. Its title gives 2000 counts and NCV. The listing states CAT III 600 V and names DC and AC voltage and current, resistance, capacitance, frequency, duty cycle, continuity, diode, temperature, live wire and NCV. The bullets add overload and short-circuit protection, an automatic shutdown after 15 minutes without operation, and a flashlight. The package includes a temperature probe, an alligator clip and a cloth pouch. Of the listings that state a count, this one has the fewest, so its display step is the coarsest, as the worked example shows. Check the Neoteck VC746A on Amazon.

Matching a meter to the job

  • Circuits above 500 V: the listings for the Fluke 87V and UNI-T UT161E state a 1000 V rating. The Hioki 3244-60 stops at 500 V.
  • Automotive and engine work: the Innova 3340 lists up to 15 A and the automotive bullets named above. Check the current range against the load before you rely on it.
  • General checks with NCV: the TESMEN TSM-599, UNI-T UT161E and Neoteck VC746A each list NCV in the listing data.

Worked example: does the rating and the display step fit the job?

Take a 480 V three-phase reading. On the Hioki 3244-60, the listed limit is 500 V, so 480 V sits at 96 percent of the rating, with 20 V of margin. On the Fluke 87V and UNI-T UT161E, the listed limit is 1000 V, so the same reading is 48 percent of the rating. The listing does not say how the Hioki behaves close to its limit, so the higher-rated meters give more margin for a reading like this.

Now the display step. A meter’s display step on a range equals the range divided by its count. On a 20 V range, a 6000-count display steps by 20 ÷ 6000 = 0.0033 V. A 22,000-count display steps by 20 ÷ 22,000 = 0.0009 V. A 2000-count display steps by 20 ÷ 2000 = 0.01 V. The UNI-T’s step is about 11 times finer than the Neoteck’s. This is arithmetic from the counts in the listings, not a measured figure, and it assumes the meter uses its full count on that range.

For current, the Innova 3340 lists up to 15 A, so a 10 A load sits at 67 percent of that rating. The UNI-T UT161E lists up to 20 A, so the same 10 A load sits at 50 percent. The Hioki listing does not state a current range.

What the listings do not say

  • Accuracy: the data we hold gives accuracy percentages for few of these six, so the table does not compare accuracy.
  • Missing ranges: the Innova 3340 and TESMEN TSM-599 excerpts do not state a voltage range, and the Hioki 3244-60 does not state a current range.
  • Durability and use: none of the listings reports drop, water or long-term results. The TESMEN and Neoteck bullets state an automatic power-off after 15 minutes. They do not say how long a battery lasts.
  • Claims we cannot check: where a listing makes a claim we cannot verify from the data, we leave it out.

Frequently asked questions

Which meter here has the highest listed voltage rating?

The Fluke 87V and the UNI-T UT161E both list AC and DC voltage up to 1000 V. The Hioki 3244-60 lists 500 V AC and DC.

Does the Innova 3340 run on batteries?

The listing’s Power Source field reads Corded Electric, but no bullet mentions a cord. The listing does not settle the question, so check the unit when it arrives.

Is the Hioki 3244-60 a full-size meter?

No. The listing describes a palm-size card meter less than 1 cm thick that weighs 0.06 kg.

How many counts does the TESMEN TSM-599 show?

The title gives 6000 counts with TRMS. The data we hold does not give a voltage range for this meter.

Which meters here list non-contact voltage detection?

The TESMEN TSM-599, the UNI-T UT161E and the Neoteck VC746A each list NCV. The Fluke 87V and the Hioki 3244-60 do not list it in the data we hold.

Conclusion

For work above 500 V, the Fluke 87V and the UNI-T UT161E are the two listings in this set that state a 1000 V rating. For a small meter to keep in a bag, the Hioki 3244-60 is the most compact. For NCV in a multimeter, check the TESMEN TSM-599, the UNI-T UT161E or the Neoteck VC746A. Before you buy, check the functions you need against the listing, because some figures are missing from the data.
