Product Overview: 725Ex Intrinsically Safe Multifunction Process Calibrator
Simple and powerful intrinsically safe calibration tool
The new 725Ex intrinsically safe multifunction process calibrator is powerful and easy to use. Coupled with one of the new Fluke-700PEx pressure modules (8), the 725Ex is capable of calibrating virtually any maintenance-required process equipment used in areas where explosive atmospheres are present.
Measure and source milliamps, voltages, temperatures (RTD and thermocouple), frequencies, ohms, and pressures using the Pressure Module option.
Do you need to calibrate a transmitter?The 725Ex split-screen display lets you view input and output values at the same time. For valve and I/P testing, you can source milliamps while measuring pressure.The 725Ex features auto-stepping and auto-sloping for remote testing, and 25% stepping for fast linear testing.
The Fluke 725Ex is ready to take and use. The controls are simple, menu-free and easy to operate. Its memory function enables quick setup. Its rugged design allows you to use it as you wish.
