The EX623A True RMS AC/DC clamp meter features two thermocouple inputs for measuring T1, T2, and T1-T2 differential temperature. It includes an infrared thermometer, a laser pointer for locating hot areas, and a Non-Contact Voltage (NCV) detector for safely testing for live electrical current. It has a DC micro-amp function that is perfect for measuring flame rods in HVAC systems, as well as capacitance measurement capabilities of up to 40 mF. The EX623A comes with test leads, a 9-volt battery, a Type K thermocouple, a bead wire temperature probe, and a carrying box.
