Fluke 725Ex Multifunction Process Calibrator
The Fluke 725Ex Multifunction Process Calibrator is an intrinsically safe multifunction process calibrator for explosion endangered areas. The Fluke 725Ex allows technicians to calibrate virtually any process instrument anticipated to require service in a location where explosive gasses may be present. Nearly all process parameters, including mA, volts, temperature (RTDs and thermocouples), frequency, ohms, and pressure, can be measured by the 725Ex utilizing optional pressure modules. The Fluke 725Ex split display enables engineers to calibrate transmitters by simultaneously seeing input and output values. Technicians can source mA while measuring pressure for tests on the valve and the I/P. In addition to 25% stepping for quick linearity tests, the 725Ex offers auto-stepping, auto-ramping, and remote testing capabilities.
