Fluke 725Ex Intrinsically Safe Multifunction Calibrator
The Fluke 725Ex intrinsically safe multifunction calibrator is powerful yet easy-to-use. Combined with one of the Fluke 750PEx pressure modules, it’s able to calibrate almost any process instrument likely to need service in an area where explosive gases may be present.
The 725Ex split display lets you view input and output values simultaneously. For valve and I/P tests, you can source mA while measuring pressure. It also has auto-stepping and auto-ramping for remote testing, plus 25% stepping for fast linearity tests.
The new 725Ex Intrinsically Safe Multi-function Process Calibrator is powerful yet easy-to-use. Combined with one of the (8) new Fluke-700PEx 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.
Measure and source mA, volts, temperature (RTDs and thermocouples), frequency, ohms, and pressure, using optional pressure modules.
Do you need to calibrate transmitters? The 725Ex split display lets you view input and output values simultaneously. For valve and I/P tests, you can source mA while measuring pressure. The 725Ex has auto-stepping and auto-ramping for remote testing, plus 25% stepping for fast linearity tests.
From the moment you pick it up, the Fluke 725Ex is ready to perform. Its simple controls, without menus, make operation easy. Its memory functions make set up fast. And its rugged design lets it work as hard as you do.
