Description

Product Details:

A loop calibration multimeter, the Fluke 789 is an essential tool for any process technician.

An upgraded version of the Fluke 787, the 789 includes all of the functionality of the 787 and builds upon it with exclusive new features. With its built-in calibration tools and a full multimeter, this process tool ensures that all of your equipment can be extensively tested and calibrated without the need to use multiple tools.

Carrying out offline transmitter testing? The Fluke 789 includes a 24V loop supply to eliminate the need to use a separate power supply. It’s also got a built-in 250Ω Hart resistor, so there’s absolutely no need to take a separate resistor along to the measurement point.

Fluke 789/E ProcessMeter Key Features:

  • 24V loop power supply
  • Large dual display with adjustable backlight for use in different lighting conditions
  • 1200Ω drive capability on mA source
  • HART mode setting with loop power and built-in 250Ω resistor
