Now compatible with Fluke Connect® App

The Fluke 789 ProcessMeter is the ultimate troubleshooting tool for electricians and instrumentation professionals, combining the functionality of a loop calibrator with the power of a digital multimeter. By equipping the 789 with a temperature measurement module and the wireless data logging capabilities of Fluke Connect® with ShareLive™ video call (sold separately), process technicians can now do a lot more while carrying a lot less. And with its built-in, selectable 250 ohm HART® resistor, it eliminates the need to carry a separate resistor with you.

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

Fluke 789 features that are also included in the Fluke 787:

  • Precision 1000 V, 440 mA True-RMS digital multimeter
  • 0.1% dc voltage accuracy
  • 0.05% dc current accuracy
  • Frequency measurement to 20 kHz
  • Min/Max/Average/Hold/Relative modes
  • Diode Test and Continuity Beeper
