The SC77 is one of our most popular digital multimeters for a reason. It has virtually every parameter for electrical and thermal HVAC/R 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, micro amps DC for flame diode tests, and everyday electrical ranges for HVAC/R. Not to mention technicians tell us it one of the most durable meters in the industry. Rivaled only by our stick meters, the SC77 is also one of their top picks from Fieldpiece.
