Top 11 Best Multimeters For Electricians
Fluke 117 Electricians True RMS Multimeter – Best Overall
Let me put it simply: The Fluke 117 Multimeter is a work of art.
Anyone who has used this multimeter before will know exactly what I’m talking about.
It. Just. Works.
Fluke’s tagline for this multimeter is literally “The Ideal Multimeter for Electricians”. I was initially sceptical – I’m sure every company thinks that their multimeter is “Ideal”.
While that may be true, Fluke’s 117 multimeter stays true to its tagline.
Everything about this digital multimeter just screams quality. The crystal clear LCD display. The LED backlight. The AutoVolt function (which autodetects AC/DC voltage for you). Its CAT III safety rating. Its intuitive and easy-to-use user interface. Its True RMS accuracy.
All the way down to the way it feels in your hand. Fluke has really outdone themselves on this one. There was clearly a lot and back and forth between electricians and the engineers at Fluke to produce this baby.
And unlike many competitors, Fluke is standing behind the quality of their devices. The Fluke 117 multimeter comes with a generous 3-year warranty.
Here’s a list of features that come with the Fluke 117:
- Measures resistance, continuity, frequency, and capacitance
- Provides Min/Max/Average to record signal fluctuations
- AutoVolt and low input impedance modes to provide faster, more accurate readings
- Features compact ergonomic design for one-handed operation
- Accurate measurements on both AC (Alternating Current) and DC current systems
- A 3-year warranty
- CAT III 600 V safety rated plus extra safety features
- A large white LED backlight to improve measurement visibility in poorly lit and low light areas
- VoltAlert™ technology for fast non-contact AC voltage detection
- Comes with a holster with probe holders for easy storage
The only downside to this digital multimeter is that it’s slightly pricier than some of the alternatives.
So if you’re looking for the best budget multimeter under $50 – grab yourself a Klein Tools MM400.
But if you’re willing to spend a bit more, then the Fluke 117 Multimeter is well worth it. This is the perfect multimeter for electricians and electronics technicians.

Another great feature is the built-in thermometer. This allows you to make temperature measurements without a separate thermometer. This is an extremely handy feature that we really wish was included in some of the cheaper Fluke multimeters.
The Automatic Touch Hold is another one of this multimeter’s stand-out features. It captures stable readings without forcing you to press extra buttons while measuring.
The Fluke 87-V records Min/Max/Average and has a Min/Max alert that automatically captures variations. The Relative mode also removes test lead interference from low-ohms measurements.
Along with a sturdy holster and case, the design element on the multimeter has a recessed dial/raised case to help protect the selector and the screen.
To complement its case, this multimeter is well proportioned; from the protected jack inputs to the uncluttered selector dial.
The Fluke 87-V is the safest digital multimeter we reviewed, with a whole host of added safety features. It has a Category IV safety rating up to 600V, and a Category III safety rating up to 1000V. It’s also been independently tested to comply with the second edition of ANSI/ISA S82.01 and EN61010-1.
This is an excellent automotive multimeter which works with both AC (alternating current) and DC systems (also known as AC current and DC current systems).
The Fluke 87V Digital Multimeter is the best premium multimeter on the market. We think Fluke knows this – that’s why the Fluke 87-V comes with a Lifetime Warranty.
Although it’s a little pricey – we can understand why. It’s absolutely packed with features (and made in the USA).

Extech EX330 Auto Ranging Mini Multimeter
The Extech EX330 is a great pocket multimeter.
It’s intuitive and easy to use buttons and interface makes it a good budget option for beginners.
We were big fans of the “Max Hold” and “Data Hold” functions, as well as its excellent auto ranging functionality.
The Max Hold function allows you to capture the multimeter’s highest reading – and the display will even update each time a higher reading is reached.
The Data Hold function allows you to freeze the current display. This is great for when you need to hold the electrical current reading while you review and take notes.
The capacitance option allows you to charge a capacitor with a known current and measure the resulting voltage when performing electrical troubleshooting.
The EX330 measures frequency between 0.001Hz to 10MHz for quick and easy diagnostics when testing circuits.
These are very useful features for electronics hobbyists. Extech has a proven track record producing high-quality products on a budget, producing one of the best megohmmeters on the market.
The built-in non-contact AC Voltage Detector is very handy for home use. This allows you to detect voltages in AC current electrical systems (note that this will not work in DC voltage current circuits).
It uses a combination of an audible beeper and red LED indicator lights to alert you to the presence of voltage when placed near live wires, outlets, and switches.
The EX330 multimeter from Extech is one of the more capable options on this list, and it is comparable to the MM400 from Klein Tools when it comes to its price.

While the Greenlee DM-45 Multimeter may not be the worst multimeter on the market, it certainly isn’t a good one.
This model is full of problems that honestly shouldn’t exist at this price point.
Let’s start with the test leads: they suck. They are way too short for comfortable use, and just scream “low-quality”. They were clearly NOT built to last. If you end up buying this multimeter, get yourself a good replacement extra long multimeter test leads.
The display is also unusable. Not only does it lack a backlight making it impossible to use at night – but it’s even hard to see during the day!
If all of this wasn’t enough, the three-minute auto-off timer combined with the relatively long startup time will drive you insane.
Not worth it – even for home use. Skip it.Check Price
