Anyone who works on their car should have a multimeter, but they come in handy around the house too.

Whether you spin wrenches for a living or only occasionally handle maintenance chores on your personal vehicles, a good multimeter is a must-have tool. Multimeters are useful for household electrical work too.

Multimeters combine different electrical testing capabilities into one unit—hence the name. At a minimum, a basic multimeter measures voltage, current, and resistance, while some offer many more functions. Analog multimeters use a needle indicator and scale to show readings, while digital multimeters (the dominant style today) show numeric readings on an LCD, LED, or other electronic display.

Multimeters can be as cheap as $10.00 but go up to thousands for professional, laboratory-quality ones. You can buy an excellent multimeter of sufficiently tough build quality and functionality for home garage use for well under $100.00.

When looking for a multimeter, you’ll want to take note of its accuracy. We prefer models that users can recalibrate to ensure they remain accurate. You should pay attention to a multimeter’s fit and finish, ease of use, safety, and the number of test functions it can perform.

Don’t forget working with electricity can be dangerous; even the 12 volts of an automotive electrical system can cause burns or other injuries. Learn to recognize electrical hazards and control them.

Here are some of the best digital multimeters you can buy. We’ve picked models with good end-user ratings and market penetration.

1. Editor's Pick: Fluke 101 Basic Digital Multimeter

Fluke’s products are featured many times on this list, as the company is definitely an industry leader. It has products on both ends of the price spectrum, but its 101 Basic Digital Multimeter is a great product for most people’s automotive and household needs and at a price that fits a reasonable budget. It’s designed for basic electrical tests, so if you’re a professional, you might want to look at a multimeter with more functionality and accessories.

Its accuracy is rated at 0.5%, 600V Cat III safety rated, and it’s small and lightweight enough for one-handed use and to fit in your tool bag. It requires 2 AAA batteries to use (batteries not included) and has automatic shutdown. Users loved this multimeter’s ease of use and reported accurate readings.

It’s important to note, however, that the screen isn’t backlit, so you will have to work in a well-lit area to use it, and it has no amp measurement.
