Extech EX840 Overview

The EX840 amp clamp has a CAT IV-600-volt, CAT III-1000V overvoltage safety rating and is CE and ETL approved. In addition to being able to take temperature measurements using the Type K wire probe, the EX840 enables users to take safe, point-and-shoot, non-contact temperature measurements with an integrated infrared (IR) thermometer that packs a useful 8:1 distance ratio. That means that at a safe distance of 8 inches users are getting a temperature reading focused on a tight, one-inch spot. The built-in IR thermometer makes it easier for users to identify overheating motors, stressed bearings, overloaded electrical panels, abnormal vent temperatures, and other components from a distance — and without an additional meter.

Other Features

The bright 4-digit, 4,000 count backlit display is complemented by several one-button functions including Data Hold, Min/Max, and selectable auto- or manual-ranging. The large 43mm jaw opening handles conductors up to 750 MCM or multiple conductors such as two 500 MCM.
