Product Description
The 725Ex intrinsically safe multifunction process calibrator is powerful yet easy-to-use. Combined with the 700PEx pressure modules, the calibrator is able to calibrate almost any process instrument likely to need service in an ex-hazardous area.
The intrinsically safe calibrator is a universal measuring instrument for process technicians which covers an extensive range of applications.
