Fluke 726 Precision Multifunction Process Calibrator

The Fluke 726 Precision Multifunction Process Calibrator is a field calibrator capable of measuring temperature, frequency, voltage and mA calculator with an accuracy 0.01%. The Fluke 726 allows users to calibrate thermocouples and RTD temperature instruments and has a built in 24V power supply. With an inbuilt memory, up to eight calibrations results can be stored on the memory for analysis.

The Fluke 726 measures and sources most process parameters to calibrate most devices. Sensors and valves can be tested and transmitters can be also be tested and calibrated and interpret results without the need for a calculator. Two separate channels even allows you to measure, source, or view process signals simultaneously.

Offering users the ability to store frequently used test setups, The Fluke 726 also allows for an RTD probe calibration contrast for enhanced temperature measurements that can be customised, with integrated input protection design that improves the reliability of the 726. A backlit display allows the use of the Fluke 726 even in challenging low lit environments.

The Fluke 726 provides a number of useful functions that allow for capturing the set, reset and dead-end of pressure switch with the integrated switch test. The % error of a calibrated transmitter can be calculated to allow for the calibration results to be interpreted. Fast linearity tests with auto step and auto ramp features and power a transmitter during a test using the 24V loop supple and simultaneous mA measurement.

Frequency totaliser and frequency pulse train source mode of the Fluke 726 allows for enhanced flowmeter testing. The HART mode inserts 250 ohm resistor in mA to measure and source for compatibility with a HART instrument.
