SC77 True RMS Clamp Meter by Fieldpiece

The SC77 is one of our most popular digital multimeters for a reason. It has virtually every parameter for electrical and thermal HVACR testing in one meter. This auto ranger includes a host of safety features including a high-voltage LED and beeper, a continuity warning, push button non-contact voltage (NCV), a lead holder with detachable leads, and alligator probe tips for easy one-handed testing. As far as ranges go, it has temperature, capacitance, microamps DC for flame diode tests, and everyday electrical ranges for HVACR. Not to mention technicians tell us it is one of the most durable meters in the industry.

Designed specifically for HVACR field service, the SC77 is a dedicated DMM and offers specific features and benefits to HVACR field service pros including:
