Compact, easy-to-use, and full-featured multimeter is a perfect tool for checking and diagnosing issues on electrical equipment, appliances, outlets, or switches. The meter measures AC/DC voltage, AC/DC current, resistance, frequency, duty cycle, and temperature as well as perform continuity and diode tests with excellent reliability and precision. Measure temperatures of refrigeration systems, heat exchangers, and line sets with the included type K thermocouple probe; select to view temperature in °C or °F.

Easily view measurements on a large 4000-count backlit LCD. Press the MIN/MAX or HOLD button to see minimum, maximum, or to freeze current reading. Use the relative measurement function to zero out the source reading to measure changes in voltage drop or temperature—ideal for identifying and diagnosing issues. Auto-shutoff feature turns off the meter after 20 minutes of inactivity, conserving battery life.
