AC/DC Clamp-on meter with built-in dual Thermocouple inputs, NCV Detector and InfraRed Thermometer

This TRMS AC/DC Clamp Meter has dual thermocouple inputs for T1, T2, T1-T2 Differential Temperature measurement plus a built-in Infrared Thermometer with laser pointer for locating hot spots and NCV Detector. Additional features include: DC micro-amp function for flame rod measurements, Diode open circuit voltage of 2.8 Volt, Data Hold plus fast Peak Hold for capturing current surges at motor startup, and capacitance measurement to 40mF.

Functional Overview

A robust 400A AC/DC “amp clamp” meter offers current load readings quickly on AC systems as well as DC systems like industrial DC motors, automotive, heavy equipment, and marine applications. An advanced, True RMS Multimeter, offers comprehensive functions for extensive troubleshooting and True RMS accuracy for measuring signals distorted by motor drives, motor controls, power supplies, and other electronic systems. An exclusive built-in infrared thermometer is ideal for quickly identifying overheating motors or locating hot spots on electrical panels, or HVAC vents without contact. A non-contact voltage detector allows yoiu to quickly and conveniently check for voltage prior to attaching the multimeter’s test leads to the device under test. A dual-input Type-K thermometer lets you get readings from two sources and calculate Delta-T with a push of a button. DMM functions include AC/DC Voltage & Current (including DC µA), Resistance, Capacitance, Frequency, Duty Cycle, and Diode/Continuity 40,000 count display.

Feature-Rich Design

Extech’s 5-in-1 clamp meter is a smart tool and a smart buy for maintenance professionals. For troubleshooting both new installations and preventive/ongoing maintenance and repairs, the EX623 accurately measures AC and DC current, voltage, and temperatures. The EX623’s infrared thermometer and laser pointer make point-and-shoot temperature readings simpler and safer. And, having two Type K thermocouple inputs makes differential temperature (delta-T) calculations like superheat and sub-cooling measurements easier to perform. For furnace and boiler maintenance flame rod current measurements, the DC microamp function is a handy surprise. The EX623’s generous 36mm jaw opening handles large conductors – up to 500MCM. The EX623 makes users’ everyday installation, diagnostic, and maintenance tasks simpler and easier – and with less toolbelt/toolbox clutter. Extech has been on the leading edge of the trend toward multifunctional instruments for several years, adding infrared thermometer capabilities into a broad range of testers and meters. Extech’s remarkable EX623 combines multiple relevant functions in one tool so technicians get more while spending less. For example, a plant professional can opt for an Extech EX623 5-in-1 clamp meter instead of buying a clamp meter plus numerous other test tools. The EX623 was designed using customer feedback – users increasingly demand multi-function capabilities in one device with no compromises.

Other Features

Powered by a 9V battery, the device has an optional Auto Power Off function to conserve battery life. The Extech measures 9 x 3.1 x 1.9 inches (H x W x D), and it weighs 11 ounces. Additionally, NIST calibration is available. The Extech EX623 5-in-1 clamp meter includes: CAT III-600V double-molded test leads; a 9V battery, two general-purpose Type K bead wire probes; a durable soft case with belt loop; and a user manual.
