Description
Fluke 726 Precision Multifunction Process Calibrator
The Fluke 726 Precision Multifunction Process Calibrator is a precise, handheld calibration device designed to deliver accurate, detailed calibration procedures within the process industry.
It is a multifunctional calibrator and can be used to measure and source voltage, mA, mV (TC terminals), resistance, frequency, loop supply, thermocouples (J, K, T, E, L, N, U, C, BP, XK, B, R and S) and multiple types of RTD. All of these functions are built into the same unit, negating the need to use additional devices during calibration procedures. It can also be used to measure and source pressure via the use of a (sold separately) Fluke 700 series Pressure Module.
This calibrator features two separate channels for measuring and sourcing/viewing process signals simultaneously, carries out measurements with precise accuracies of just 0.01% and includes a large selection of additional functions such as HART mode, custom RTD curves, the ability to test transmitters and much more.
It also includes limited memory functions and can store up to 8 calibration results and can store pre-set calibration procedures for ease of use in repeat testing.
