The Best Multimeter Options for DIYers and Pros


From testing batteries to determining the amount of voltage in an electrical circuit, the multimeter is a standard diagnostic tool often found in electricians’ tool kits. But multimeters also come in handy for DIYers who want to test their home’s wiring or repair electrical appliances. They’re also practical for hobbyists—folks who like to tinker with electronic circuits in the building of things like pedometers, motors, and humidity sensors.

Prior to the development of multimeters (also called multitesters), individual meters were used to test circuits for voltage (voltmeter), resistance (ohmmeter), and current (ammeter). Today’s multimeters combine those testing capabilities into a single tool, letting you perform a variety of electrical tests with one device.

A wide variety of multimeters are available, designed for both basic and advanced circuit testing and geared toward different projects and/or specialties. While a DIYer can usually get by with a no-frills tool, electricians and HVAC pros will benefit from some of the advanced options found on professional models. Read on to learn what to look for and to find out why we recommend the favorites listed below:

The Best Multimeter Options for DIYers and Pros

Key Considerations

Basic and Advanced Functions

For greatest versatility, make sure the multimeter you buy is capable of testing both types of electrical current, alternating current (AC)—the electricity that flows through the outlets in your home—and direct current (DC), the electricity found in batteries. Additionally, in order to qualify as a multimeter, the tool must perform at least two of the following three basic electrical tests:

  • Current: The electricity’s rate of flow
  • Voltage: The difference in electric current between two given points
  • Resistance: How much the material carrying the energy, such as wires, resists electrical flow

In addition to testing voltage, resistance, and current, advanced digital multimeters often come with the ability to test the following:

  • Capacitance: The ability to store an electrical charge
  • Temperature: The physical warmth of the circuit (often in both Fahrenheit and Celsius)
  • Frequency: The rate of electrical occurrence (measured in hertz)

Analog Versus Dial Display 

The classic analog multimeter features a dial with a needle (like the old-time speedometer on a car), and for some, this type of readout is easier to see, especially in bright sunlight when numbers on a digital display can be difficult to decipher. You won’t find a large selection of analog meters anymore, but they’re typically inexpensive, ranging from $10 to $70, and they can perform the three basic circuit tests; they don’t have the capability to perform more advanced testing.

Most multimeters on the market today are digital, and they’re a bit pricier, ranging from $20 to $500, or even more, based on quality and precision. Some digital multimeters come with a backlit screen that makes the display easier to see in bright light, and some include an auto shut-off feature that turns the meter off after a few minutes of nonuse.

Auto-Range Function

Figuring out the approximate range of the electrical current you’re testing with a manual range multimeter can be a time-consuming process. If you want to test resistance, for example, you must first estimate the approximate ohms (Ω) of the current by turning the dial to a specific ohms range, then keep clicking manually until the multimeter gives you a readout. A multimeter with an auto-range function (available only on digital models) will save you time, since all you have to do is select the type of test you want to perform (voltage, resistance, or current). The meter will then automatically detect the correct range by scanning through all the range options until it matches the right range to the circuit, and a readout appears immediately.

Tips for Choosing the Best Multimeter

Probes and Accessories

Most multimeters include a set of standard red and black probes for performing basic tests, others come with additional alligator clips for attaching the probes to wires or battery terminals. A magnetic case or sling is a handy accessory that allows the user to attach the multimeters to something metal, such as a cabinet or the undercarriage of a car, letting you see the readout and still have both hands free for testing. These clips, probes, and cases are also available at hardware and home improvement stores.
