Fluke 725Ex Intrinsically Safe Multifunction Process Calibrator – Electrical, Temperature, Frequency and Pressure Calibration

General
The Fluke 725Ex is an intrinsically safe multifunction process calibrator designed for testing and calibrating process instrumentation in hazardous and potentially explosive environments. It provides versatile measurement and sourcing capabilities for electrical and temperature signals, making it suitable for industrial maintenance, commissioning and calibration applications.

The calibrator measures and sources mA, voltage, resistance, frequency, thermocouple and RTD signals. It also supports pressure measurement and calibration when connected to compatible Fluke intrinsically safe pressure modules, which are available separately. Its dual-display interface allows users to monitor input and output signals simultaneously during transmitter testing and calibration.
