Fluke 789
Double Your Power

The Fluke 787 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 the Fluke 789 – the ultimate loop calibration multimeter. The Fluke 789 has a 24-Volt loop supply reducing the need for taking a separate power supply when doing offline transmitter testing. And with its built-in, selectable 250-Ohm Hart® resistor, it also eliminates the need to carry a separate resistor with you. Now process technicians can do a lot more while carrying a lot less.

Features of the Fluke 789
  • 24 V Loop power supply
  • Very large dual display
  • Enhanced backlight with 2 brightness settings
  • 1200 ohm drive capability on mA source
  • HART mode setting with loop power and a built-in 250 ohm resistor
  • 0% and 100 % buttons to toggle between 4 and 20 mA sourcing for a quick span check
  • Externally accessible fuses for easy replacement
  • Infrared-port to process data in FlukeView Forms (V2.1) software
