EXTECH EX623 Digital Multimeter with Infrared Thermometer

The Extech EX623 is a versatile digital multimeter featuring a built-in infrared thermometer with laser targeting and an 8 to 1 distance-to-target ratio for detecting hot spots. It includes dual Type K thermocouple inputs for measuring temperatures and differential temperature readings, essential for superheat calculations. The device also has a built-in non-contact AC voltage detector with LED alerts, True RMS measurement capability for accurate readings on distorted or noisy signals, and a DC current function suitable for automotive, heavy equipment, and marine applications. Additional functions include DC voltage, resistance, capacitance, and frequency measurements, as well as a DC microamp measurement mode for HVAC/R flame rod currents. With a basic accuracy of 0.06%, a high-resolution 40,000-count LCD display, data hold, and fast peak hold features, it can measure motor capacitors up to 40,000 µF and conductors up to 500 MCM with a 1.25-inch (32mm) jaw opening. The multimeter also encompasses auto power-off with an audible alert, a disable function, and a CAT III 600V safety rating.
