Product overview: Fluke 726 Precision Multifunction Calibrators

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:

  • A backlit display provides better visibility in poor light • Stores frequently-used test setups for later use
  • Program custom RTD probe calibration constants of certified RTD probes for enhanced temperature measurement
  • Voltage input protection design for improved reliability
  • Three-year warranty
  • Features frequency totalizer and frequency pulse train source mode for enhanced flowmeter testing
  • Measures volts, mA, pressure, RTDs, thermocouples, frequency, and resistance to test sensors and transmitters
  • Sources/simulates volts, mA, thermocouples, RTDs, frequency, and pressure to calibrate transmitters
  • Measures or sources pressure using any of 50 Fluke 750P series Pressure Modules
  • Sources mA with simultaneous pressure measurement to conduct valve and I/P tests
  • Provides two separate channels to measure, source and view process signals simultaneously
  • Provides an integrated pressure switch test to allow you to capture the set, reset, and deadband of a switch
  • Provides transmitter error % calculation to interpret calibration results without a calculator
  • Performs fast linearity tests with auto-step and auto-ramp features
  • Powers transmitters during test using 24 V loop supply and simultaneous mA measurement

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.

Reviews: Fluke 726 Precision Multifunction Calibrators

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.

Rated 1 out of 5 by from Fluke 726 I replaced the battery and the numbers froze on the screen and then I try to turn it back on it wouldn't come on at all it wwas in my trunk I don't know why it wouldn't come on

Rated 5 out of 5 by from Great Multifunction Calibrator We have been using model 725 and 726 Fluke Multifunction Calibrators for over 8 years now. This is a simple and user friendly instrument that I carry on my tool case on a daily basis. We recommend this product greatly, we have been working with Fluke products for over 25 Years.
