    1000A Current Testing and Quick Infrared Temperature Spot Checks

    The rugged Extech EX840 1000A AC/DC CAT IV clamp meter is designed to deliver safety and versatility — without compromising performance or innovation. You can take the EX840 on the job to leverage its advanced meter functions including True RMS AC/DC current and voltage, resistance, capacitance, frequency, infrared and contact temperature, diode-test, and continuity check. Use the EX840’s fast-responding peak hold function to capture inrush currents and transients.

    Functionality 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 1.7-inch (43mm) jaw opening handles conductors up to 750 MCM or multiple conductors such as two 500 MCM.
