EX623 5-in-1 Combination Clamp Meter with Built-in Infrared Thermometer


Extech’s 5-in-1 clamp meter is specifically designed for HVAC/R and electrical professionals in residential, commercial, institutional, and industrial settings. The EX623 accurately provides non-invasive measurements of AC and DC current, voltage, and temperatures for troubleshooting both new installations and preventive/ongoing maintenance and repairs. No other clamp meter offers the convenience and versatility of 5 meters in one instrument: AC/DC clamp meter; high resolution True RMS multimeter with wide ranges for Capacitance and Diode checking; non-contact infrared thermometer (Extech-patented); non-contact voltage detector; and dual Type-K thermometer for differential temperature measurements.

The EX623’s patented infrared thermometer and laser pointer make temperature readings simpler and safer. And, having two Type K thermocouple inputs make differential superheat and sub-cooling temperature measurements easier to perform. The DC microamp function is ideal for flame rod current measurements and the EX623's generous 36mm jaw opening handles conductors up to 500MCM. To make users’ everyday installation, diagnostic, and maintenance tasks simpler and easier, Extech’s EX623 offers users a valuable combination of 5-in1 convenience, a rugged double-molded housing, competitive pricing, top-spec capabilities, and less toolbelt/toolbox clutter that no other brand can offer. Extech’s 5-in-1 redefines expectations about clamp, multimeter, voltage detector, IR thermometer and Differential Type-K thermometer functionality and form factor. Users increasingly demand multi-function capabilities, one device, with no compromises.
