Electrical Testers

Klein Tools MM400 is an auto-ranging millimeter that measures AC/DC voltage, AC/DC current, and resistance. It can also measure temperature, capacitance, frequency, duty-cycle, and test diodes and continuity. Klein Tools' Test and Measurement product line was exclusively designed from the ground up by electricians for electricians. Years of field research, combined with extensive input from electricians across America, inspired the development of meters and electrical testers loaded with innovative, time-saving features.

  • MultiMate was developed to withstand daily wear and tear on the job site and is a professional meter that provides accurate readings
  • Safety rating is CAT III 600-Volt, class 2, double insulation
  • Built to endure a 3.3 ft. (1 m) drop
  • Multimeter meets requirements for use in basic and controlled electromagnetic environments such as residential properties, business premises, and light-industrial locations
  • Includes low battery indicator and has easily accessible battery compartment
  • Operating temp: 32°F to 104°F (0°C to 40°C)
