The Klein Tools MM420 is an auto-ranging digital multimeter designed by electricians for electricians. This reliable meter measures AC/DC voltage, AC/DC current, and resistance—the core functions every electrician needs on the job. Beyond basic measurements, it also tests temperature, capacitance, frequency, duty cycle, diodes, and continuity, making it a versatile tool for troubleshooting electrical circuits and equipment in residential, commercial, and light industrial settings.

The MM420 features a CAT III 600V safety rating that provides reliable protection when working with hazardous circuits. The meter includes a low-battery indicator so you'll know when to swap batteries, and convenient lead holders and a kickstand for hands-free operation. An optional magnetic hanger is also available for mounting.
