Process calibration designed specifically for process industries

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 to test and calibrate transmitters. The 726 interprets results without the help of a calculator and stores measurement data for later analysis.

Measurement capabilities

This precision multifunction calibrator measures volts, mA, pressure, RTDs, thermocouples, frequency, and resistance to test sensors and transmitters. The 726 also sources and simulates volts, mA, thermocouples, RTDs, frequency to calibrate transmitters. Measures and/or sources pressure using when paired with any of the 50 Fluke 750P series Pressure Modules to test and calibrate pressure transmitters and other devices. The 726 can also:

  • Source mA with simultaneous pressure measurement to conduct valve and I/P test
  • Conduct enhanced flowmeter testing with frequency totalizer and frequency pulse train source mode

Designed for ease of use

The 726 has built-in features that make it easier to use in nearly any measurement situation. From its ability to store frequently used test setups, to programming custom RTD probe calibration constants for enhanced temperature measurement, or the integrated voltage input protection design that improves reliability, the 726 is built to perform. The use of two separate channels even allows you to measure, source, or view process signals simultaneously. The backlit display provides better visibility in low-light conditions, and the standard 3-year warranty provides extra confidence that the 726 will be there when you need it to be.

You can also use the 726 to:

  • Capture the set, reset, and deadband of a pressure switch with the integrated switch test
  • Calculate the transmitter error % to interpret calibration results without the use of a calculator
  • Perform fast linearity tests with the auto-step and auto-ramp features
  • Power a transmitter during test using 24 V loop supply and simultaneous mA measurement

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

Rated 5 out of 5 by from Portable and powerful I bought this calibrator 6 months ago. It is very convenient to make typical operations and more convenient than Fluke 725 calibrator. I don't need the user manual almost at all operations, I just do my work. But there are some questions to the Fluke 726 calibrator. 3- or 4-wire RTD measurement is not so easy because you have to connect "+mA" terminal (red) and "COM" terminal (black) to the low end and "-mA" terminal and "V" terminal to the high end of the resistor. It is annoying me. Typical 3-wire connections use two wires to the high end and one wire to the low end of the resistor. Fluke 726 connection with reverse wire order doesn't look trivial.
