This True RMS AC/DC clamp meter combines the dual thermocouple inputs for T1, T2, and T1-T2 differential temperature measurement with a built-in infrared thermometer and a laser pointer for pinpointing hot spots.
The Non-Contact Voltage (NCV) detector adds a layer of safety, while the DC micro-amp function is ideal for flame rod measurements in HVAC systems, and its capacitance measurement capability extends up to 40 mF.
The Extech EX623A includes test leads, a 9 V battery, two Type K bead wire temperature probes, and a carrying case.
