April 7, 2015 | By Renée Francoeur

April 7, 2015 – Extech Instruments, makers of handheld test and measurement tools, have introduced the EX850, a 1000A AC/DC CAT IV clamp meter with Bluetooth technology and a built-in infrared thermometer.

With Extech’s ExView app and the clamp meter, contractors and plant maintenance professionals can remotely view and display readings from the meter on an Android phone or tablet up to 10 m, or 30 ft away.

“Remote viewing on an Android device offers a host of advantages,” said Samuel Ruback, product manager at Extech Instruments. “Listening to customers, we hear stories of job sites with awkward testing situations that can make it difficult to view a meter’s display. Firing up the EX850’s app on a tablet or smartphone tackles these challenges.”

The EX850’s True RMS meter functions include AC/DC current, voltage, resistance, capacitance, frequency, infrared and contact temperature, diode-test, and continuity check. The EX850’s peak hold function captures inrush currents and transients.


The 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-in. jaw opening handles conductors up to 750MCM or multiple conductors such as two 500MCM.

The EX850 has a CAT IV-600V, CAT III-1000V overvoltage safety rating and is CE approved. The meter comes complete with a CAT IV test leads, a 9V battery, Type K temperature probe, and a belt holster.
