The mid-size essential clamp meter has virtually every parameter for electrical and thermal HVACR testing in one meter. This auto and manual 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 it is one of the most durable meters in the industry.
