Amprobe AM-520 HVAC Multimeter

Designed primarily for HVAC professionals, the AM-520 autoranging digital multimeter offers all the most commonly used HVAC digital multimeter features such as temperature, micro amps to troubleshoot flame sensors, and capacitance to check motor startup capacitors. With its CAT III safety rating, this high voltage multimeter measures a broad range of electrical parameters. The backlit LCD display makes it easy to read, and it’s easy to use with non-contact voltage detection, the “third hand” probe holder, and the built-in flashlight.
