Fluke 789 Process Meter

Fluke 789 Process Meter

The Fluke 789 Process Meter is a rugged, all-in-one solution for electrical and instrumentation professionals. It combines a digital multimeter with loop calibration capabilities, allowing for greater efficiency in field diagnostics. The dual backlit display shows both mA and % of scale readings, helping to speed up troubleshooting tasks.

Equipped with a selectable 250 ohm HART resistor and built-in 24 V loop power, the Fluke 789 Process Meter eliminates the need for additional tools during transmitter testing. This makes it ideal for process technicians aiming to streamline their toolkits and reduce carry weight. The unit offers externally accessible fuses and battery access for added convenience.

Versatile Measurement and Calibration

With full DMM functionality, this meter measures voltage, resistance, current, and frequency up to 20 kHz. It also supports diode testing, continuity checks, and various data hold functions. The 4–20 mA sourcing and simulation features include manual and automatic stepping, ramping, and span check buttons for 0% and 100% output.

Wireless-Ready and Built for Field Work

The Fluke 789 Process Meter is compatible with the Fluke Connect app using the IR3000 FC adaptor (sold separately), allowing remote data logging and sharing. It is built to the CAT III 1000 V / CAT IV 600 V safety standard and comes with a 3-year warranty, making it a reliable choice for demanding environments.
