About the Extech EX850 Features:

The rugged Extech EX850 1000A clamp meter is designed to deliver safety and versatility — without compromising performance or innovation. You can take the EX850 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. 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. For quick, point and shoot temperature readings, you can also use the EX850’s non-contact IR thermometer with laser pointer for fast temperature checks or hot-spot detection. The EX850 amp clamp has a CAT IV-600-volt, CAT III-1000V overvoltage safety rating and is CE and ETL approved.
