Compact Digital Multimeter for Professional Use

The Klein Tools MM400 Multimeter is an auto-ranging multimeter that can measure AC/DC voltage, AC/DC current, and resistance up to 40 MOhms. In addition to these functions, it is also capable of measuring temperature, capacitance, frequency, duty-cycle, and can test diodes and continuity. The Test and Measurement product line from Klein Tools has been designed exclusively by electricians for electricians. This product line was developed after years of field research and extensive input from electricians across America, resulting in meters and electrical testers that are equipped with innovative, time-saving features.

The Multimeter can measure up to 600V AC/DC voltage, 10A AC/DC current, and 40 MOhms resistance. It is also equipped with an electrical tester that can measure temperature, capacitance, frequency, duty-cycle, and can test diodes and continuity. With a CAT III 600V safety rating, this product is built to withstand a 3.3-foot (1 m) drop and daily wear and tear on the job site. It also features a low battery indicator and an easily accessible battery compartment. Designed for use in basic and controlled electromagnetic environments such as residential, business, and light-industrial locations, the Multimeter includes test leads, a thermocouple with adapter, batteries, and a user manual.
