Fluke 718Ex Intrinsically Safe Pressure Calibrator

Available in 30G, 100G, and 300G Pressure Ratings


Potentially explosive atmospheres can be found in a variety of manufacturing environments from chemical or pharmaceutical processing, to oil refineries—or any environment where flammable material (gas or dust/particulates) are present. Fluke’s intrinsically safe test tools can be used to help you perform maintenance and calibration tasks in potentially explosive and hazardous classified areas. Fluke offers the widest range of reliable, accurate and intrinsically safe test tools. Including true-rms multimeters, infrared thermometers, process calibrators, pressure calibrators, loop calibrators and precision pressure test gauges.

The Fluke 718EX 300 Intrinsically Safe Pressure Calibrator measures pressure via a 1/8-Inch NPT pressure fitting and an internal pressure sensor or via Fluke 700PEX Series Pressure Modules. The calibrator simultaneously displays pressure and current measurements, performs switch testing and measures current up to 24 mA.

The calibrator's unit button selects a different pressure unit. All units are available when the pressure sensor input is used. The damp button turns pressure reading damping on and off. With damping on, the calibrator averages several measurements before displaying a reading. The Calibrator automatically turns off after 30 minutes of inactivity.

This equipment is specified for use in measurement category I (CAT I) pollution Degree 2 environments and should not be used in CAT II, CAT III, or CAT IV environments.-voltage transients should not exceed 300-volts for the CAT I applications where this product is used. Do not use in a damp or wet environment.
