# 726
Fluke 726 Precision Multifunction Process Calibrator designed specifically for the process industry
The Fluke 726 is a precise and powerful, yet easy-to-use field calibrator. It features broad workload coverage, calibration power, and unsurpassed accuracy needed by process professionals. It measures and sources almost all process parameters to calibrate almost anything. Use it to test sensors and valves and test and calibrate transmitters. The 726 interprets results without the help of a calculator and stores measurement data for later analysis.
Other useful features:
If you need an intrinsically-safe rated calibrator, consider the Fluke 725Ex Intrinsically Safe Multifunction Process Calibrator.
If you want documenting and HART communication built into your calibrator, consider the Fluke 754 Documenting Process Calibrator with HART.
