Fluke 707Ex Intrinsically Safe Loop Calibrator

The fastest, one-handed tool for mA loop checks in Ex zones.

The Fluke 707Ex is an intrinsically safe loop calibrator for use in explosion endangered areas, it has all the features of the standard Fluke 707 plus an ATEX rating.

Fluke 707Ex Intrinsically Safe Loop Calibrator is a high performance solution for calibration, repair and maintenance of current loops.  Use it to temporarily replace the power source in a current loop. With the calibrator in control of the current, you can accurately set the current between 4 and 20 mA. This allows you to control the loop and the devices connected to it — which means you can control and calibrate actuators and indicators in that loop

Click your way to the precise milliamp value you want with Fluke 707's "Quick Click" knob interface making it extremely fast and easy to use. Each click changes the value by 0.001 mA. Press and click to change it in increments of 0.100 mA. The large digital display shows you. The click lets you feel it.

The Fluke 707Ex is certified in accordance with the ATEX directive (Ex II 2 G Eex ia IIC T4) in Zones 1 and 2. The Fluke 707Ex is also certified to operate in accordance with Factory Mutual N.I. Class 1, Division 2 areas Group A-D.

What is “intrinsically safe”?

Intrinsic safety is a protection method employed in potentially explosive atmospheres. Devices that are certified as “intrinsically safe” are designed to be unable to release sufficient energy, by either thermal or electrical means, to cause ignition of flammable material (gas or dust/particulates).
