How to use this list

Three specs separate these meters more than anything else: the CAT safety rating (where on the electrical system you may safely measure), whether AC readings are True RMS, and the display count. The table below puts all three side by side, straight from each maker's specifications, so you can rule meters in or out before reading the ranked write-ups. If you already know the job, the best multimeter for electricians and best multimeter for home use guides rank the same pool for that work, and our beginner ranking favors the easiest meters to learn on.

The Fluke 117, 115 and 87V are the three meters here we have bought and tested ourselves. The Fluke 117 review and Fluke 87V review cover two of them in depth, and Fluke 115 vs Fluke 117 explains when the cheaper sibling is enough. On a budget, our budget True RMS multimeter ranking narrows the field to affordable meters that keep True RMS. If you are unsure whether you need a clamp meter as well, start with the clamp meter buying guide, and the multimeter buying guide explains each spec from scratch.

From each maker's page, datasheet or manual. "Not claimed" means the maker doesn't describe the meter as True RMS; "Not stated" means the figure isn't in our verified data. The Fluke 117/323 Kit pairs two meters already in the table. The Klein MM450's CAT IV figure on listings applies to its leads; the meter itself is CAT III 600V.

How much each meter weighs

Weight is a fair proxy for the trade-off between pocket carry and a rugged, full-size case. The palm-sized Flukes come in at well under half the weight of the 115 and 117, but they give up True RMS to get there, and the 101 drops current measurement entirely. The Klein MM450 is the light option that keeps True RMS.

#13Best Pocket Fluke4.3★★★★☆

Fluke 107

A palm-sized Fluke with CAT III 600V and a 6,000-count display, but not True RMS.

Best for:A compact second meter, home and auto checks

The Fluke 107 is a 200 g, palm-sized meter rated CAT III 600V, with a 6,000-count backlit display, capacitance, frequency and duty cycle, and a 1 m drop rating. Fluke states plainly that it is not True RMS, so on variable-speed drives and electronic loads its AC readings are less trustworthy than a 115 or 117. It suits a glovebox or toolbag second meter, or anyone who mostly checks batteries, outlets and continuity.

#15Best Value Fluke4.5★★★★★

Fluke 17B+

A full-size Fluke with temperature, frequency, MIN MAX and relative mode, but not True RMS.

Best for:Electronics hobbyists, students, appliance repair

The 17B+ is Fluke's feature-rich entry meter: CAT III 600V (CAT II 1000V), a 4,000-count backlit display, auto and manual ranging, and functions the 117 lacks, including temperature with the supplied Type K probe, frequency to 100 kHz, duty cycle, capacitance to 1,000 µF, MIN MAX and relative mode. Fluke doesn't call it True RMS, so on drives and electronic loads its AC readings are less dependable than a 115 or 117. Note that the Amazon listing's photo shows the newer 17B MAX, so check which model it ships.

#16Best Basic Fluke4.3★★★★☆

Fluke 15B+

The 17B+ body and safety rating without frequency, temperature or MIN MAX: a plain, tough Fluke for volts, amps and ohms.

Best for:Basic electrical and electronics checks

The 15B+ shares the 17B+'s case, CAT III 600V / CAT II 1000V rating, 4,000-count backlit display, 10A current ranges and 1,000 µF capacitance, but drops frequency, duty cycle, temperature, MIN MAX and relative mode. That makes it a straightforward, durable meter for checking voltage, current, resistance and continuity. Like the 17B+, Fluke doesn't describe it as True RMS.

#17Best Budget Pocket Fluke4.2★★★★☆

Fluke 106

The 107's palm-sized body for less, without diode test, frequency or duty cycle.

Best for:A small, cheap backup meter

The 106 is the 107's simpler sibling: the same 142 × 69 × 28 mm, 200 g body, CAT III 600V rating and 6,000-count display, with 4A and 10A current ranges, resistance to 40 MΩ, capacitance to 1,000 µF, continuity and data hold. It drops the 107's diode test, frequency and duty cycle, has no mA or µA ranges, and Fluke positions it for work where True RMS isn't needed.

#18Smallest Fluke4.1★★★★☆

Fluke 101

Fluke's smallest, simplest meter: volts, ohms, capacitance and frequency in 160 g, but no current measurement at all.

Best for:Voltage and continuity checks only

The 101 is Fluke's most basic meter: 130 × 65 × 27 mm and 160 g, CAT III 600V, a 6,000-count display, 600V AC/DC, resistance to 40 MΩ, capacitance, frequency to 100 kHz, duty cycle, diode and continuity, with a 1 m drop rating. It has only two input jacks and cannot measure current, and Fluke doesn't call it True RMS. It isn't sold on Fluke's US site, so the Amazon listing comes from a third-party importer, and it carries a one-year warranty rather than two.

#19Best Electrical Tester4.4★★★★☆

Fluke T5-600

Not a multimeter but an electrician's tester: volts, continuity and up to 100A AC through an open jaw, no leads in the circuit.

Best for:Electricians' quick voltage and current checks

The T5-600 is an electrical tester rather than a multimeter. It reads up to 600V AC or DC with automatic AC/DC selection, resistance to 1,000 Ω, continuity, and up to 100A AC through its OpenJaw current fork, so you can check a load's current without breaking the circuit. It is CAT III 600V, survives a 3 m drop, and stores its probes in the back. It is average-responding rather than True RMS and has no capacitance, frequency, diode or DC current.

#20Best Fluke Clamp Meter4.7★★★★★

Fluke 323

A True RMS clamp meter for current measurement without breaking a circuit open — a different tool than a standard multimeter, not a replacement for one.

Best for:Fast current checks without breaking the circuit

The Fluke 323 reads AC current up to 400A by clamping around a conductor, with True RMS accuracy on non-sinusoidal loads. It doesn't measure DC current, capacitance, or frequency, and has no backlight or temperature mode — it's built specifically for clamp current work, not as a general-purpose meter. See our clamp meter buying guide for when this matters over a standard multimeter.

Methodology

How we chose

We started from the multimeters most often recommended by electricians and hobbyists, then compared CAT safety rating, True RMS, resolution, and extras like NCV and low-impedance mode against the work each kind of buyer actually does.

Specs from the sourceEvery spec is checked against the manufacturer's official product page or datasheet and the official Amazon listing. Where sources disagree, we say so.
Fit over feature countEach pick earns its place for a specific kind of buyer, and we name who should skip it, rather than ranking on spec-sheet length.
Owner feedback, cross-checkedWe look for patterns in verified-purchase reviews to catch reliability issues that spec sheets never show.
No sponsored picksWe earn mainly from Amazon affiliate commissions and may also show display ads from Google. No brand or advertiser can pay for a spot, a ranking or a badge, and ads never affect our picks.

Picks marked "Hands-on Tested" have been bought and tested by us; the rest are desk research. A pick only carries that badge once we have actually bought and tested that unit. More on how we research.

Questions

Frequently asked questions

What does a CAT rating mean?+

CAT (Category) ratings indicate how much transient voltage spike a meter is rated to safely withstand. CAT III 600V is the standard recommendation for home electrical panels and most residential wiring work. CAT IV covers the utility side: service entrances, meter bases and outdoor feeds. A meter and its test leads are only as safe as the lower of their two ratings.

Do I need True RMS?+

True RMS matters if you're measuring non-sinusoidal signals — common with modern electronics, variable-speed motors, and dimmer switches. For basic DC continuity checks, it's less critical. An average-responding meter is calibrated for a clean sine wave, so on a distorted waveform it can read noticeably high or low, which is why HVAC and drive work call for True RMS.

Should I get a clamp meter instead of a standard multimeter?+

A clamp meter measures current by clamping around a wire — no need to break the circuit open, which is faster and safer for everyday checks. It's a great addition to a standard multimeter, not usually a replacement, since clamp meters are less practical for resistance, continuity, and low-current work.

What does 6,000-count mean on a multimeter?+

The count is the largest number the display can show before it switches range. A 6,000-count meter reads up to 5,999, so a 5 V rail shows as 5.000 V on its 6 V range. A 4,000-count meter tops out at 3,999, so the same 5 V lands on the 40 V range and reads 5.00 V, one digit less. For most household work either is fine; for electronics, the extra digit helps.

What is a LoZ (low-impedance) mode and do I need it?+

A normal meter input is very high impedance, so it can show a voltage on a disconnected wire that is only capacitively coupled to a live one, often called ghost voltage. LoZ mode loads the circuit enough to drain that phantom reading, so you see whether the conductor is really live. Electricians who test in shared conduit benefit most. Here, the Fluke 117 and Brymen BM235 have it; the Fluke 115 does not.

Is an expensive Fluke more accurate than a budget meter?+

Not always on a simple DC reading: a good budget True RMS meter such as the UNI-T UT139C will read a battery or a 12 V supply perfectly well. Where the premium meters pull ahead is verified safety ratings, input protection, durability and higher-category ratings like the CAT IV 600V on the Fluke 87V and 179. Pay for those if you work on mains or panels; for low-voltage hobby work, the budget picks are enough.
