Fluke 789 Process Meter

Designed for Process Technicians

The Fluke 789 ProcessMeter™ is built for process technicians and industrial instrumentation engineers who need both a high-performance digital multimeter and a loop calibrator in one compact tool. Designed for commissioning, maintenance and troubleshooting of process control systems, it simplifies testing by combining electrical measurements with mA loop sourcing and simulation.

 

Accurate Process Calibration

Measure True RMS AC/DC voltage, current, resistance, continuity and frequency while sourcing, simulating and measuring 4–20 mA current loops. The integrated 24 V loop power supply and HART mode support make the 789 ideal for testing transmitters, valves and PLC systems without carrying separate instruments.

 

Improve Efficiency in the Field

With CAT IV 600 V / CAT III 1000 V safety, Fluke Connect® compatibility (with optional IR3000FC adapter) and dedicated calibration functions, the Fluke 789 helps process technicians diagnose faults faster and reduce the amount of equipment they need on site. How does the Fluke 789 improve everyday maintenance? It combines precision electrical testing and loop calibration into one rugged instrument, saving time on every job.
