Overview

The Fluke 725EX is part of Fluke’s intrinsically safe series of calibrators. It allows technicians to measure and source volts DC, mA, RTDs, thermocouples, frequency, and ohms, making it a versatile tool for transmitter calibration, valve testing, and I/P device verification. Moreover, it is certified for Class I, Division 1 Groups B–D hazardous areas, ensuring safe operation in explosive atmospheres.

Technical Data

Typical Applications

• Transmitter calibration with simultaneous source and measure functions.

• Valve and I/P testing by sourcing mA while measuring pressure.

• Hazardous area maintenance in oil & gas, petrochemical, and chemical plants.

• Pressure device calibration using intrinsically safe Fluke 700PEx pressure modules.

• Process troubleshooting with dual-channel display for input/output verification.

FAQ

Q1: What makes the 725EX different from the standard Fluke 725?
