Our top picks at a glance
Fluke 117 True RMS Multimeter — Best Overall
$250.58
Check price on Amazon →PROS
- ✓ Built-in non-contact voltage detector
- ✓ AutoVolt AC/DC auto-switching
- ✓ Low impedance mode eliminates ghost voltages
- ✓ Industry-recognized — inspectors never question it
CONS
- ✗ No current clamp — need separate tool for amps
- ✗ Highest price in the group
The Fluke 117 is the meter most journeymen recommend and most commercial job specs require. True RMS, built-in NCV, low-Z mode, and Fluke durability. If you want one meter that never gets questioned, this is it.
Klein CL800 Digital Clamp Meter — Value Pick
$139.96
Check price on Amazon →PROS
- ✓ Clamp meter + multimeter in one tool
- ✓ AC/DC current up to 600A
- ✓ True RMS with low impedance mode
- ✓ Temperature, capacitance, frequency included
CONS
- ✗ No built-in NCV
- ✗ Slightly less durable feel than Fluke
The Klein CL800 packs more measurement capability per dollar than anything else on this list. If you can only carry one meter, the CL800 covers the most ground — voltage, current, resistance, temperature, and more.
Klein MM700 Autoranging Multimeter — Budget Pick
$107.16
Check price on Amazon →PROS
- ✓ True RMS at the lowest price in the group
- ✓ Autoranging with low-Z mode
- ✓ Temperature and capacitance measurement
- ✓ Durable enough for daily field use
CONS
- ✗ No NCV detector
- ✗ No current measurement (needs separate clamp)
At around $107, the Klein MM700 is the most affordable True RMS multimeter worth recommending to a working electrician. It has the core features — low-Z mode, autoranging, temperature — without the Fluke price tag.
Fluke 323 True RMS Clamp Meter — Best Fluke Clamp
$168.88
Check price on Amazon →PROS
- ✓ Fluke build quality and calibration
- ✓ 400A AC clamp for current readings
- ✓ True RMS for accurate readings
- ✓ Compact and easy to use one-handed
CONS
- ✗ No DC current measurement
- ✗ No low-Z mode
- ✗ Fewer features than Klein CL800 at higher price
The Fluke 323 is the entry point into Fluke clamp meters. Fewer features than the CL800, but Fluke reliability and the brand recognition that matters on job sites where equipment specs matter.

How we chose these meters
We focused on meters that working electricians actually use daily — not hobbyist tools or industrial-only equipment. Every meter on this list is True RMS, rated CAT III 600V minimum, and available through standard electrical supply channels and Amazon. We weighted measurement capability, build quality, safety ratings, and real-world value.

Frequently Asked Questions
What is the best multimeter for a first-year apprentice?
The Klein CL800 is the best starting point. It combines a clamp meter and multimeter so you only need to buy one tool, and it costs less than a Fluke 117 alone. As you advance, you can add a dedicated Fluke multimeter.
Do I need True RMS?
Yes. Non-True-RMS meters give inaccurate readings on non-linear loads like VFDs, LED drivers, and modern electronics. Every meter on this list is True RMS, and any meter you buy for professional electrical work should be too.
What is low impedance mode and why does it matter?
Low impedance (low-Z) mode uses a lower input impedance to bleed off stray voltage that can cause false readings. It eliminates ghost voltages on open circuits. The Fluke 117, Klein CL800, and Klein MM700 all have this feature.
Can I use a cheap multimeter for electrical work?
A cheap meter may give inaccurate readings on modern loads and may not have proper safety ratings. More importantly, an uncertified meter with inadequate arc-flash protection can be dangerous. Stick with CAT III 600V rated meters from reputable brands.
