Fieldpiece Loaded Swivel Clamp Meter - SC620


SC620 Loaded Swivel Clamp Meter by Fieldpiece

The SC620 swivel-head clamp meter is packed with all the electrical measurements HVACR professionals use everyday. It also includes a host of safety features like 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, the SC620 clamp meter has temperature, capacitance, and microamps DC for flame diode tests. It's a rugged workhorse you can count on to get the job done easier, faster, and more safely.

The SC620 is fast reacting, easy-to-use, and rugged, with extended temperature tolerances that allow for testing in freezers and on hot rooftops.Designed specifically for HVACR field service, the SC620 is a dedicated digital multimeter that offers specific features and benefits to help HVACR professionals do more, everyday:
