Fluke 789
Processmeter
Description
This Processmeter was the first tool to combine a DMM and a loop calibrator to give process technicians double the power in one tool.
Now it’s even better, the range is extended with this unit, the ultimate loop calibration multimeter.
This unit has a 24Volt loop supply reducing the need for taking a separate power supply when doing offline transmitter testing.
And with its built in, selectable 250ohm Hart resistor, it also eliminates the need to carry a separate resistor with you.
