The 707Ex is an intrinsically safe loop calibrator for use in explosion endangered areas. The Fluke 707Ex is certified in accordance with the ATEX directive (Ex II 2 G Ex ia IIC T4) in Zones 1 and 2.

• Large display and simple, quick-click interface for easy one-handed operation
• Simultaneous mA and % readout for quick, easy interpretation of readings
• mA accuracy of 0.015%, superior to other loop calibrators in this price range
• 1 µA resolution for mA source, simulate and measure
• Push button 25% steps for fast, easy linearity checks
• 0 - 100% “span check” for fast confirmation of zero and span
• Selectable slow ramp, fast ramp, and step ramp to provide smooth outputs for valve slewing and loop functional tests
• 24 volt internal loop supply, so you can power and read a transmitter at the same time without carrying a DMM
• Measures V DC to 28 V
• Single 9 V battery that is easily changed without braking calibration sea
• 0 - 20 mA or 4 - 20 mA default start up modes
• Innovative output adjustment dial with 1 µA and 100 resolution
• HART ™ mode connects 250 Ω resistor in series with 24 V loop for compatibility with HART communicators
