Fluke 707Ex Intrinsically Safe Loop Calibrator

The Fluke 707Ex Intrinsically Safe Loop Calibrator is a fast response, one-handed instrument designed to allow you to safely perform mA loop checks in potentially hazardous explosive areas.

Fully certified in accordance with ATEX directive EX II 2 G Ex ia IIC T4 for use in zone 1 and 2 applications, the Fluke 717Ex includes all of the functionality you’ll need for loop calibration applications, with reliable, accurate and safe results every time it is used.

Fluke’s 707Ex calibrator includes a wide variety of diferent functions – it can be used to measure voltage from 0 to 28V with resolution of 0.001V, can be used to measure, source and simulate mA and also functions as a loop supply up to 24V DC.

This loop calibrator has many other additional extras – it can simultaneously display mA and % readouts, has a push button with 25% steps for linearity checks, can be used to perform 0-100% span checks and it is also has HART compatible resistance suitable for connection in series with the loop supply for compatibility with HART communicators.
