Best Multimeter That Reads Microfarads

As an Amazon Associate we earn from qualifying purchases. Details

A multimeter that reads microfarads has a capacitance mode, and the number that matters is the range it covers, because a mode that tops out at 40 microfarads is no use for a 70 microfarad part. The six listings below were all opened on 2026-10-17, and every figure comes from the listing text, including where a listing contradicts itself. Only four of them state a capacitance range. The other two name capacitance without giving one, so I say so in the card rather than guess. “Best for” means the best fit for the stated job, not a result from my own bench, because I have not run these meters.

Quick answer

If you want the widest stated capacitance range of the group in a handheld multimeter, look at the AstroAI 6000-count model, which lists ranges from 60nF up to 60mF. If you want a well-known brand with a stated range of 1000 microfarads, the Fluke 17B+ is the one. If you want a low-cost meter with the range and accuracy spelled out, the AstroAI DM130B covers 40nF to 400uF with accuracy printed for each range. If you want a clamp for AC current as well, the AstroAI 2000-count clamp lists capacitance up to 2mF. The AstroAI M4K0R and the Crenova MS8233D name capacitance but give no range in the text I read.

What “reads microfarads” means

Capacitance is measured in farads, and meters work in small fractions of one. A microfarad (µF, written uF in some listings) is one millionth of a farad. A nanofarad (nF) is one thousandth of a microfarad, and a millifarad (mF) is a thousand microfarads. The listings use all three, which is why they can look more different than they are: 400nF is 0.4 uF, 2mF is 2000 uF and 60mF is 60,000 uF.

A multimeter usually splits capacitance into ranges, and each range has its own accuracy. The DM130B listing shows the pattern. Its 40nF range is stated as ±(8%+10), its 400nF, 4uF and 40uF ranges as ±(5%+5), and its 400uF range as ±(8%+10). The “+10″ or “+5″ is a count of display digits added on top of the percentage, so a meter with more counts can show finer steps. Your target is to find a meter whose highest range is above the largest part you will test, and whose accuracy in the range you use is acceptable.

What to check before you choose

The stated range, and whether it exists

Four listings print a range. Two do not. The M4K0R page lists “Capacitance Measurement” in its highlights, and the MS8233D page lists capacitance among its functions, but neither prints the range in the text I read. That does not mean the function is weak. It means you cannot judge it from the listing and should check the manual or ask the seller. Compare each meter’s top range with the largest part you test, not with the lowest.

Accuracy per range

Only two listings print accuracy for capacitance. The DM130B gives it per range, as above. The 2000-count clamp gives a single figure of ±(4.0%+5) across its seven ranges from 2nF to 2mF. The Fluke listing prints the range in a comparison table and does not print an accuracy figure in the text I read.

Safety wording

The listings print CAT III 600V for the Fluke, the DM130B, the M4K0R, the MS8233D and the clamp, and the 6000-count AstroAI prints both CAT III 600V and CAT II 1000V. The Fluke title also advertises 1000V voltage measurement, while its bullet rates it CAT III 600V, so read the rating and the measurement range as two separate things.

Capacitors are a separate safety question. Virginia Tech’s Environmental Health and Safety department says capacitors may store hazardous energy even after the equipment has been de-energized. Discharge a capacitor using the procedure in your meter’s manual or from a qualified technician before you connect a meter to it, and leave any work on mains-connected equipment to a licensed professional. See the university’s capacitor safety page for its guidance.

Weight and listing contradictions

Three listings give two different weights. The DM130B says approximately 185 g with the battery in one field and 9.9 ounces in another, which is about 281 g. The 6000-count AstroAI says approximately 357 g and 1.08 pounds, which is about 490 g. The clamp says approximately 203 g and 14.6 ounces, which is about 414 g. The cards show both so you can see the gap.

The six listings

Worked example: does the range cover the part?

For example, suppose you want to check a capacitor marked 45 uF. Compare it against the stated ranges. The DM130B tops out at 400uF, so a 45 uF part falls in its 400uF range, where the listing prints ±(8%+10). With a 3999-count display on that range the last digit is 0.1 uF, so “+10″ is about 1.0 uF, and 8% of 45 uF is 3.6 uF. That is a planning estimate of roughly ±4.6 uF, so a reading between about 40.4 and 49.6 uF fits that stated accuracy. The Fluke’s 1000 uF range and the 6000-count AstroAI’s ranges also cover 45 uF, but their listings do not print an accuracy figure for capacitance. The 0.1 uF digit size is my inference from the range and the count, not a figure from the listing, so check the meter’s manual for the real resolution.

Frequently asked questions

Which of these states the widest capacitance range?

The 6000-count AstroAI states ranges up to 60mF, which is 60,000 uF. The clamp meter states 2mF (2000 uF), the Fluke 17B+ states 1000 uF, and the DM130B states 400uF.

Do all of them print a capacitance range?

No. The M4K0R and the MS8233D name capacitance but do not print a range in the text I read.

What does 400uF in a listing mean compared with 2mF?

A millifarad is a thousand microfarads, so 2mF is 2000 uF. A meter listed to 400uF cannot read a 2000 uF part, but a meter listed to 2mF can.

Is it safe to connect a meter to any capacitor?

Not without discharging it first. Virginia Tech’s Environmental Health and Safety department says capacitors may store hazardous energy even after the equipment has been de-energized, so follow the discharge steps in your manual or from a qualified technician.

Final recommendation

For the widest stated range, the 6000-count AstroAI. For a recognized brand with 1000 uF stated, the Fluke 17B+. For accuracy printed per range up to 400uF, the DM130B. For AC current plus capacitance in a clamp, the 2000-count AstroAI clamp. The M4K0R and MS8233D are general meters that name capacitance without a range, so confirm the range before you rely on either. Match the top range to your largest part, check the stated accuracy in the range you use, and discharge every capacitor before connecting a meter.
