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.
