The SC680 is the top of the line clamp meter with wireless functionality for the HVACR professional. Send your electrical measurements directly to the Job Link® System mobile app. Leave the meter behind a closed blower door and view the current measurement on your mobile device. The only meter you’ll need for troubleshooting mini-split systems. Dual Type K temperature ports to measure entering/exiting air temperatures and measure frequency (Hz) directly with clamp jaw. Reach those cramped mini-split connectors with the included RCT2 probe tips for voltage and resistance measurements. Hang your SC680 clamp meter to any metallic surface with the heavy-duty magnet. When the job is done, store your test leads in the back case for tidy and convenient storage. See both voltage and amperage readings at the same time on the large dual display. Easily see your amperage readings no matter how you clamp around a wire with the swivel head AAC clamp.
