Get twice the power with the Fluke 789 ProcessMeter!

Features & Applications:

Fluke combined a loop calibrator and a DMM to give process technicians double the power in one tool. Now we made it even better – the ultimate loop calibration multimeter – the Fluke 789 ProcessMeter. The 789 has a display that's not only twice as large, but also twice as bright with two levels of backlighting. With its built–in, selectable 250 ohm HART® resistor, it eliminates the need to carry a separate resistor with you. Now process technicians can do a lot more while carrying a lot less.

Features:

  • 24 V Loop power supply
  • HART mode setting with loop power (adds 250 ohm resistor)
  • 100 % larger dual display
  • 1,200 ohm drive capability on mA source
  • Enhanced backlight with two brightness settings
  • 0-100 % mA Span Check buttons to toggle between 4 and 20 mA
  • Infrared I/O serial port compatible with FlukeView® Forms Software Version 2.1
  • Externally accessible fuses for easy replacement
  • DMM designed to meet 1000 volt IEC 1010 CAT III standards
  • Precision 1000 V, 440 mA true-rms digital multimeter
  • Frequency measurement to 20 kHz
  • Min/Max/Average/Hold/Relative modes
  • Diode Test and Continuity Beeper
  • Simultaneous mA and % of scale readout
  • 20 mA dc current source / loop calibrator / simulator
  • Manual Step (100 %, 25 %, Coarse, Fine) plus Auto Step and Auto Ramp
  • Externally accessible battery for easy battery changes
  • Includes:
    • Fluke 789 Process Meter
    • TL71 Premium Test Lead Set
