Fluke 707Ex Intrinsically Safe Loop Calibrator

Fluke 707Ex Intrinsically Safe Loop Calibrator

The Fluke 707Ex is an intrinsically safe loop calibrator for sourcing, simulating and measuring 4-20 mA signals in hazardous areas. Certified to the ATEX directive for Zones 1 and 2, it lets instrument and maintenance technicians calibrate transmitters, valves and loop devices in potentially explosive atmospheres without leaving the area or shutting the process down. A single rotary push-button keeps the workflow fast in awkward field conditions.

Brand and standards

Fluke is one of the most trusted names in electrical test and measurement, and Powerpoint Engineering is an authorised Fluke distributor in Ireland. The 707Ex carries ATEX certification for use in Zone 1 and Zone 2 hazardous areas, so it is suited to oil and gas, chemical, pharmaceutical and other process sites where intrinsic safety is mandatory. It delivers superior accuracy of 0.015%, and our in-house laboratory can keep it within specification with traceable calibration.

Applications

The 707Ex covers everyday loop work where an intrinsically safe instrument is required:

• Calibrating 4-20 mA transmitters and process instruments in Zone 1 and Zone 2 areas
• Sourcing or simulating mA signals to check valves, recorders and control inputs
• Measuring loop current and DC voltage during commissioning and fault-finding
• Driving loops directly using the internal loop supply where no separate power is available
• Ramp testing instruments with slow, fast and step ramp functions

Specifications

Key features

• Simple, convenient interface with an easy-push rotary button and knob
• Simultaneous reading of mA and percentage
• 1 microamp resolution for mA source, measured or simulated
• Innovative output adjustment dial for fine control
• HART compatible for use with smart instruments

FAQs

Is the Fluke 707Ex safe to use in a hazardous area?

Yes. The 707Ex is intrinsically safe and certified to the ATEX directive for Zone 1 and Zone 2, so it can be used in potentially explosive atmospheres such as oil and gas, chemical and pharmaceutical sites where ordinary calibrators are not permitted.

Can the 707Ex both source and measure 4-20 mA signals?

Yes. It can source or simulate mA with 1 microamp resolution and measure loop current, and it reads DC voltage to 28 V. Default start-up modes are 0-20 mA or 4-20 mA, and the internal loop supply lets you drive a loop with no separate power.

Can Powerpoint Engineering calibrate my Fluke 707Ex?

Yes. Our in-house calibration and repair laboratory services Fluke calibrators and issues traceable certificates. Speak to our calibration team to book your 707Ex in.
