Fluke Multifunction Process Calibrator 725

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. You can also perform both temperature and pressure transmitter calibrations.

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 and the backlit display provides better visibility in poor light. It features a small, streamlined shape and a rugged, reliable design that makes it ideal for standing up to harsh field conditions.

Versatile troubleshooting tool

Power transmitters during test using the loop supply with simultaneous mA measurement so you can test a transmitter out of circuit and better isolate problems. The 725 can also test a variety of fast pulsed RTD transmitters and PLCs (Programmable logic controllers), with pulses as short as 10 ms.

Source mA with simultaneous pressure measurement to conduct valve and I/P (Input current/Output pressure) tests in a single device. You can also test flow meters with frequency and CPM (counts per minute) functions and perform fast linearity tests with auto-step and auto-ramp features so you can quickly verify the mA signal at different output levels.

For more precision, pulse sourcing, and pulse counting (totalizing), consider the Fluke 726 Precision Multifunction Calibrator.

For documenting and HART communication built into your calibrator, consider the Fluke 754 Documenting Process Calibrator with HART.
