Fluke 789 Overview and Features

Fluke 789 Overview and Features

Double Your Energy

The Fluke 789 was the first device to blend a DMM and a loop calibrator to give process professionals double the energy in one device. Now it’s even better, the range is extended with the fresh Fluke 789 - the greatest loop calibration multimeter. The Fluke 789 features a 24-Volt loop supply lowering the need for taking a separatepower supply when performing offline transmitter assessment. With its built-in, selectable 250-Ohm Hart® resistor, it also eliminates the need to have a individual resistor along with you. Now process specialists can perform far more while carrying a lot less.
