The Fieldpiece SC440 True-RMS AC/DC Clamp Meter features virtually every parameter for electrical and thermal HVACR testing in one meter. This auto and manual-ranging meter includes a host of safety features including a high-voltage LED and beeper, continuity warning, push button non-contact voltage (NCV), 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.

The SC440 can be attached to any metallic surface with the heavy-duty magnet strap for hands-free operation. Both voltage and amperage readings can be viewed simultaneously with the dual display that features a bright blue backlight for reading in low-light conditions. The single test lead holder enables added safety and the automatic clamp jaw light allows the user to easily view the wire that needs to be tested.

More accurate VAC and AAC readings on VFDs can be obtained with the True-RMS sensing technology of the SC440. With the Inrush current feature, the user can measure the starting amp draw of a compressor.

The SC440 is built to withstand the rigors of HVACR service with the high-impact plastic construction and display able to be read in both hot or cold environments. The high temperature resistance allows the user to move from a cold freezer to a hot rooftop and still obtain accurate temperature measurements.
