The Fluke 725Ex Intrinsically Safe Process Calibrator is powerful yet easy-to-use. Combined with one of the (eight) Fluke 750PEx Pressure Modules, the 725Ex is able to calibrate almost any process instrument likely to need service in an area where explosive gasses may be present.
Specifications: Fluke 725Ex Series Process Calibrator
