The Best Multimeters
The multimeter is one of the most essential tools in the electrician's toolbox. A versatile device, most multimeters combine a DC voltmeter, AC voltmeter, ammeter, and ohmmeter all into one. If you're looking to add a multimeter to your tool chest, you've probably already noticed that there are tons of features and prices to consider. But don't stress: that's where we come in. We did the research, read the literature, and came up with a list of the best of the best in the world of multimeters.
What to Look For
In our search for the best multimeters, we used four main questions to guide us: Does it deliver accurate and fast readings? Is the design portable? From voltage to capacitance, what different units can it measure? Is the price fair for the quality? With these considerations in mind, the Kaiweets digital multimeter emerged as our favorite overall option since it has a long-lasting build and a wide range of accurate readings. But if you prefer the reliability of old-school analog multimeters, we recommend checking out Gardner Bender’s GMT-319 model, which proves the enduring value of analog devices. There’s a lot to consider, so let’s dive in.
Kaiweets Digital Multimeter
Pro design for a bargain
If you’re looking for a digital multimeter that covers all the bases, look no further than the Kaiweets digital multimeter. Designed for industrial, automotive, and household use, this multimeter features a “6,000-count” resolution for highly accurate readings of current, voltage, frequency, resistance, capacitance, continuity, wire on-off, liquid temperature, and even battery life. In addition, the thermistor protection circuit and double ceramic fuse help prevent burns, so it’s as safe as it is functional.
Pros:
- Live function with light and sound alarm
- Clear, 2.9-inch LCD backlight display
- Stable kickstand for hands-free use
Cons:
- The voltage meter defaults to AC
Gardner Bender GMT-319 Multimeter Tester
Classic and reliable
Sometimes, old school is best. Nothing exemplifies this better than Gardner Bender’s GMT-319 multimeter. The color-coded displays are easy to read, while the 20-position rotary dial provides simple and easily-verifiable switching. The plastic-coated leads with long, exposed tips are also replaceable, meaning you don’t have to purchase an entirely new multimeter if the leads break or are lost. And at only 2 inches wide and with a weight of 12 ounces, it’s also the perfect multimeter to slip into your toolbox for quick testing of batteries, outlets, and circuits on the go.
Pros:
- Accurate
- Super portable
- Reliable and easy to read
- Replaceable fuse and leads
Cons:
- The analog display is accurate, but digital displays are often easier to read in low lighting
Klein Tools MM700 Multimeter
Troubleshooting made simple
The MM700 from Klein Tools is a “mean-squared digital multimeter,” which means it’s one accurate device. This multimeter packs a full arsenal of tools and accessories, including a replacement thermocouple, an extra fuse (rare in most multimeters), a right-angle replacement lead test set, a nylon carrying case, and a magnetic hanger. Loaded with innovative and time-saving features, the Klein Tools MM700 multimeter is worthy of professional electricians.
Pros:
- Handy kickstand for visibility
- Large backlit display with a 4,000-count LCD
- Super durable construction can withstand drops
Cons:
- No dedicated transistor test function
Siglent Technologies SDM3045X 4-1/2 Digit Digital Multimeter, DMM
Upgrade your shop
When you need absolute precision and calibration, the SDM3045X multimeter from Siglent Technologies can serve you well. Featuring a 4.5-digit reading resolution and a 150 rdgs/s max measurement speed, you can be sure your readings have unmatched accuracy. Built with 1GB NAND flash storage, it also has vast storage potential for data files. Better yet, the LAN and USB remote interfaces make it compatible with other popular DDMs on the market as well. Get accurate readouts by histograms, trend charts, bar charts, statistics, and more.
Pros:
- Precision up to 100MHz
- Extremely accurate readings
- Resistance measurement down to 0.01 ohms
- The interface is advanced yet surprisingly intuitive
Cons:
- It’s expensive, though the professional quality is worth it
Frequently Asked Questions
Are digital multimeters inherently better than analog ones?
There’s actually only one difference between digital and analog multimeters: digital multimeters display their readout on an LCD screen, while analog units utilize a needle scale. This can make the digital instrument easier to read. The circuitry inside the multimeter is the same for both units, so their accuracy is only a function of the readout, not a function of the unit itself. That said, an analog multimeter can detect sudden fluctuations that may occur in the electrical flow (as indicated by a bouncing needle). Since digital units only give one reading, they can’t perform this function.
Do analog multimeters lose their accuracy over time?
Many analog multimeter manufacturers guarantee the accuracy of their products for a year. After that, the DMM might not keep its accuracy within the specified limits. If you want to be sure your multimeter consistently gives you accurate readings, recalibrate it at least once per year.
