600 A Dual Input Clamp Meter with IR Thermometer and NCV

Extech EX623A

Model: EX623A Go to Product Support

The EX623A True RMS AC/DC clamp meter combines dual thermocouple inputs for T1, T2, and T1-T2 differential temperature measurement. It comes with a built-in infrared thermometer and a laser pointer for pinpointing hot spots and a Non-Contact Voltage (NCV) detector, so you can safely check for live electrical current. It features a DC micro-amp function that is ideal for flame rod measurements in HVAC systems, and its capacitance measurement capability extends up to 40 mF. The EX623A comes complete with test leads, a 9 V battery, Type K thermocouple, bead wire temperature probe, and a carrying case.
