Volt Meter Amp Meter: 5 Handheld Meters Compared

As an Amazon Associate we earn from qualifying purchases. Details

This roundup looks at the same five volt amp meters as the companion post, but from the handheld side of the job: weight, size, power and how the meter is held. The figures vary a lot across the five, and two of them are clamp meters rather than meters with test leads. Each figure is taken from the listing’s own fields and is shown as the seller gives it. Figures were checked on 11 October 2026.

Quick answer: the AstroAI is the lightest at 0.15 kg, with the ANENG at 155 g and the LJPXHHU at 166 g close behind. The FNIRSI clamp is the only one whose listing describes a rechargeable battery. The Klein CL120 is the heaviest at 9.76 ounces, and its included-components field lists the clamp alone.

How we chose these five

All five results are volt amp meters with a handheld body, so none was removed. The same five appear in the companion post on current ranges, so the picks overlap with that post. The weight and size figures are taken only from the listing fields. We did not test any of these meters, and nothing below reports personal use. Where a size field looks wrong, the note says so.

1. AstroAI Digital Multimeter Tester 2000 Counts

The listing gives a weight of 0.15 kg, which is the lightest of the five. It runs on two 1.5 V AAA batteries and has a silicone cover that the listing says protects the meter from damage. Its size field reads 1.77 by 5.47 by 42.52 inches. The last figure is far larger than a handheld meter, so treat that field as a likely listing error and confirm the size with the seller. Check the AstroAI 2000 Count on Amazon.

2. LJPXHHU Digital Multimeter XL830L

The listing gives a weight of 166 g and a size of 5.51 by 2.56 by 1.18 inches. It says the meter can be held in the hand or stood on its fold-out stand, and that the rubber cover is designed to be slightly non-slip. The display is a 2.7 inch backlit LCD. The listing names car repair, home use and similar work as typical uses. Check the LJPXHHU XL830L on Amazon.

3. ANENG Digital Multimeter with Case SZ301

The listing gives a weight of 155 g and includes a case, which the title confirms. No size is stated in the text used for this post. Its battery test covers 12 V, 9 V and 7.5 V batteries, and the listing describes auto shut-down to save power. A 2000 count LED screen shows the readings. Check the ANENG SZ301 on Amazon.

4. FNIRSI DMC-100 Clamp Meter

The listing gives a weight of 6.72 ounces and a size of 7.7 by 2.91 by 1.14 inches. It runs on a 1500mAh rechargeable lithium battery that charges through a Type-C cable, and the listing says it keeps running during long jobs without a wait for a recharge. The 2-inch display can switch between dark and light themes. The package includes a clamp meter, two multimeter pens, a temperature probe and the charging cable. Check the FNIRSI DMC-100 on Amazon.

5. Klein Tools CL120 Digital Clamp Meter

The listing gives a weight of 9.76 ounces and a size of 8.45 by 3.51 by 1.51 inches. The clamp jaws open around a conductor to read current. The listing describes a backlit display for low-light work and auto power-off after 10 minutes to save the battery. Its included-components field lists the clamp meter and its 400 amp AC range, with nothing else. Check the Klein CL120 on Amazon.

Worked example: comparing the two clamps by weight

Convert the two clamp weights to the same unit to compare them. One ounce is about 28.35 grams, so the Klein’s 9.76 ounces comes to about 277 grams (9.76 times 28.35 is 276.7). The FNIRSI’s 6.72 ounces comes to about 190 grams (6.72 times 28.35 is 190.5). The FNIRSI is therefore about 69 percent of the Klein’s weight (190.5 divided by 276.7 is 0.69). The AstroAI’s 0.15 kg is about 150 grams, which is 54 percent of the Klein’s weight, so it is the lightest of the five by a clear margin.

What the listings do not say

None of the five listings gives a drop test or a durability test. The AstroAI size field looks like a listing error, and the ANENG listing states no size at all. The weight figures do not say whether the batteries are included, and the listings do not state that consistently.

Frequently asked questions

Which is the lightest meter in this set?

The AstroAI at 0.15 kg. The ANENG follows at 155 g and the LJPXHHU at 166 g.

Is the FNIRSI clamp lighter than the Klein clamp?

Yes. Its listed weight of 6.72 ounces is lower than the Klein CL120’s 9.76 ounces.

Which meter here recharges?

The FNIRSI DMC-100 listing describes a rechargeable lithium battery with a Type-C charging cable. The other four listings do not describe a rechargeable battery.

Does the Klein clamp come with a case?

Its included-components field lists the clamp meter alone. The listing does not state a case, so check the package on arrival.

Why does the AstroAI size look wrong?

Its size field gives 42.52 inches as one dimension, which is far too long for a handheld meter. It is probably a listing error, so confirm the size with the seller before you buy.

Conclusion

For the smallest handheld meter, the AstroAI and ANENG listings state the lowest weights. For a clamp that is easier to carry than the Klein, the FNIRSI listing gives a lower weight and a rechargeable battery.
