Best Dc Clampmeter

This roundup covers the DC clamp meters in the research file for a DC clampmeter search. The file holds five listings, and three of them state DC current. The AstroAI and Neoteck listings say they measure AC current only, so they are not picked. Figures are copied from the listings as the sellers state them and dated 11 October 2026. Where a listing gives two figures that do not match, both are shown.
Quick answer: for small DC currents such as battery leakage or a parasitic draw, the VIVANTECH and EITAI listings both state 1 mA resolution on a 60 A range. For a DC current above 60 A, the FNIRSI DMC-100 is the one pick here whose listed range reaches 600 A.
The three DC clamp meters at a glance
| Clamp meter | DC current (as listed) | Low-current figure | Best fit |
|---|---|---|---|
| FNIRSI DMC-100 (B0DP2L9CFR) | AC and DC up to 600 A | Not stated | Wide range and logging |
| VIVANTECH Low Current (B0FRMKT79S) | AC and DC, 1 mA to 60 A | 1 mA resolution | Parasitic draw and fuse circuits |
| EITAI6000B Leakage Clamp (B0DJZX321M) | DC and AC, 0 to 60 A | 1 mA resolution | Leakage with USB data upload |
How we chose these three
We kept listings that state a DC current figure in the title, bullets or specification table. The AstroAI listing says its clamp cannot test DC current, and the Neoteck listing gives its 600 A figure for AC current only. Both are left out. A figure a listing does not state is reported as not stated. We did not check any of these clamps in person.
- DC range: the highest DC current each listing states.
- Resolution: the smallest step the listing gives, which matters for small leakage currents.
- Accuracy and extras: any accuracy figure, memory or data output the listing names.
1. FNIRSI DMC-100 Clamp Meter
The DMC-100 is listed as a true RMS clamp meter for AC and DC current up to 600 A, with voltage, resistance, capacitance, frequency and temperature. Its title gives 9999 counts, while a bullet gives 10000 counts, and both are shown here. The listing names graph recording that stores 8 sets of real-time data and 30 sets of history. The listing gives no resolution figure for DC current. It has a 2 inch color screen and a built-in 1500 mAh battery that charges from a Type-C cable. The listing says voltage must be measured with the test leads, and that the jaws are for current only. It weighs 6.72 ounces. Checked 11 October 2026.
2. VIVANTECH High Accuracy Low Current Clamp Meter
The VIVANTECH clamp is listed for both AC and DC current from 1 mA up to 60 A, with a 1 mA resolution. Its title names automotive electrical diagnosis and power maintenance. The listing says it recognizes AC or DC automatically, with a manual switch if needed, and that it measures without breaking the circuit through a 16 by 18 mm jaw. The bullets name battery leakage, motor start-up current and wiring leakage as uses. It has a one-button zero, data hold, 99 memory groups and a backlit LCD. The listing gives automatic power-off after 5 minutes of inactivity. It weighs 7.04 ounces and measures 8.5 inches long, 2.4 inches wide and 1.3 inches deep. Checked 11 October 2026.

3. EITAI6000B DC/AC Leakage Clamp Meter
The EITAI6000B is listed for DC and AC current from 0 to 60.0 A, with a 1 mA resolution and an accuracy of plus or minus 2 percent of reading plus 5 digits. The title gives an 18 mm figure, and the specification table gives a jaw of 16 by 18 mm. The listing gives a 4 digit LCD, a sampling rate of 2 times per second, 99 memory groups and a USB port for uploading stored data. It lists a line voltage below 600 volts and a CAT III 600 volt standard. The clamp runs on a 9 volt battery that the listing says is not included. It weighs 220 g. Checked 11 October 2026.
Worked example: the error on a small leakage reading
For example, take the EITAI’s accuracy figure at a 50 mA reading. Plus or minus 2 percent of 50 mA is 1 mA. The 5 digit allowance is 5 steps of its 1 mA resolution, which is another 5 mA. Together that is plus or minus 6 mA, so a 50 mA display means the true current lies between 44 and 56 mA. These are arithmetic results from the listed figures, not a test.
The range is the second check. A 100 A DC current is above the 60 A limit of both the VIVANTECH and the EITAI, so neither can read it. The FNIRSI listing gives a 600 A limit, so the same 100 A current sits well inside it, but its listing gives no resolution at that small end of the range.
What the listings do not say
None of the three listings gives an independent accuracy test. The FNIRSI listing gives no DC resolution, and the VIVANTECH listing does not state an accuracy figure. The EITAI listing gives its accuracy, but does not say how it is affected by a nearby wire carrying current. Check the rating on the meter before use, and keep the leads and clamp jaw clean so the reading stays steady.
Frequently asked questions
Can these clamp meters measure DC current?
Yes. The FNIRSI DMC-100, the VIVANTECH and the EITAI6000B listings all state DC current. The AstroAI listing says its clamp cannot test DC current, and the Neoteck listing states AC current only.
Which of these picks reads the smallest DC current?
The VIVANTECH and the EITAI6000B both list a 1 mA resolution, which is the finest step in this group. The FNIRSI listing gives no resolution figure for DC.
Is the EITAI meter able to store readings?
Yes. The listing says it stores 99 groups of readings and can upload them to a PC over USB. The VIVANTECH listing also names 99 memory groups and recall, but does not mention a USB upload.
What battery does the EITAI clamp need?
The listing says it runs on a 9 volt battery, Zn-Mn type, and that the battery is not included because of import rules. Buy one before you start a test.
Why are the AstroAI and Neoteck listings left out?
The AstroAI listing says its clamp cannot test DC current, and the Neoteck listing gives a 600 A figure for AC current only. A DC clampmeter search needs a DC current figure, so those two listings do not fit.
Conclusion
For small DC leakage or a parasitic draw, the VIVANTECH and the EITAI6000B are the two picks with a 1 mA resolution on a 60 A range. For DC current above 60 A, the FNIRSI DMC-100 is the pick whose listing reaches 600 A. Check the DC range and the resolution against the current you need to measure, and confirm the rating on the meter before use.
