Fluke 789 Process Meter, DMM & Loop Calibrator

The Fluke 789 Process Meter is the industry-standard tool for process technicians, combining the power of a digital multimeter (DMM) with a full-featured loop calibrator. By merging two essential tools into one rugged, portable unit, the 789 saves time, reduces tool count, and simplifies fieldwork.

With its integrated 24 V loop power supply, the Fluke 789 can source, simulate, and measure mA signals while powering transmitters, making it ideal for calibration and troubleshooting of process loops. In addition to its process functions, the 789 offers high-accuracy electrical testing, including voltage, resistance, continuity, and diode checks.

Featuring a large dual display, intuitive controls, and optional Fluke Connect™ compatibility (via IR3000 adapter), this process meter enables easy setup, reliable data logging, and wireless data sharing. Built tough for industrial environments, it provides unmatched efficiency and reliability for process control and instrumentation professionals.
