Designed primarily for HVAC professionals, the Amprobe AM-520 HVAC Multimeter offers all the most commonly used HVAC digital multimeter features such as temperature, microamps to troubleshoot ember 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 right of access, and it's neighboring to as soon as non-agreement voltage detection, the third-hand study holder, and the built-in flashlight.
