This Fluke 707Ex mA Loop Calibrator is in used, very good cosmetic condition. The unit has passed all self-checks and is fully functional.

The calibrator sources, simulates and measures 4–20 mA and 0–20 mA current loops with 0.015% accuracy, and measures DC voltage to 28 V. It carries full ATEX certification (Ex II 2 G Ex ia IIC T4, Zones 1 and 2) and Factory Mutual N.I. Class 1, Division 2 Group A–D approval for use in hazardous and explosive environments.

The following items are included:
• Fluke 707Ex mA Calibrator unit
• High quality aftermarket test leads (banana plug with probe tips)

The Fluke 707Ex is an intrinsically safe mA loop calibrator designed for use in potentially explosive environments. It is certified to the ATEX directive (Ex II 2 G Ex ia IIC T4) for Zones 1 and 2, and to Factory Mutual N.I. Class 1, Division 2 Groups A–D, making it one of the most widely trusted hazardous area loop calibrators available.

The 707Ex combines the best features of push-button and knob-based loop calibrators for extremely fast, accurate, one-handed operation. The large display provides simultaneous mA and percentage-of-span readout. An internal 24 V loop supply allows the user to power and read a transmitter simultaneously without a separate DMM. HART-compatible resistance is connected in series with the loop supply for use with HART communicators. Selectable slow, fast, and step ramp outputs support valve slewing and loop functional testing. Push-button 25% steps enable fast linearity checks, and a 0–100% span check confirms zero and span rapidly. The 9 V battery can be replaced without breaking the calibration seal.
