Product Details

Fluke 725 Multifunction Process Calibrator

Key features

Powerful, easy-to-use field calibrator

Measures volts, mA, pressure, RTDs, thermocouples, frequency, and ohms to test sensors and transmitters

Sources/simulates volts dc, mA, thermocouples , RTDs, frequency, ohms, and pressure to calibrate transmitters

Measures/sources pressure using any of 50 Fluke 750P Pressure Modules

Easy to read measure/source screen displays input and output simultaneously

Product overview

The Fluke 725 Multifunction Process Calibrator is simply powerful!

With the Fluke 725 Multifunction Process Calibrator you can easily source and measure almost any process parameter and test almost any process device. Measure and source mA, volts, temperature (RTDs and thermocouples), frequency, ohms, and pressure, using optional pressure modules.

From the moment you pick it up, the Fluke 725 is ready to perform as a powerful, yet easy-to-use field calibrator. Its simple controls, without menus, make operation easy.

Other useful features
