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.
Features:
• True RMS for accurate measurements of AC voltage and current measures
• 600 A AC/DC Current
• Low Impedance (LoZ) to improve accuracy reduce the possibility of ghost voltages
• Low Pass Filter (LPF) to ensure more accurate readings in noisy electrical environments
• Inrush (100 ms) current feature to capture start-up current
