Product Overview

The Fluke 725 Multifunction Process Calibrator is a versatile, easy-to-use calibrator designed for testing and troubleshooting a wide variety of process instrumentation.
Compact yet powerful, it can source and measure mA, voltage, RTD, TC, frequency, ohms, and pressure (using external pressure modules), making it ideal for technicians who need a reliable, field-ready tool.

Unlike the 726, the Fluke 725 is optimized for simplicity and speed, with dedicated function keys and a user-friendly interface that allows quick switching between measurement and source modes—perfect for everyday process calibration tasks.
