Fluke 789 ProcessMeter

The Fluke 789 ProcessMeter doubles troubleshooting capabilities by combining the power of a safety-rated digital multimeter and an mA loop calibrator into a single, compact test tool. Based on the trusted measurement capabilities of the Fluke 87 DMM, the 789 adds the ability to measure, source, and simulate mA with exceptional accuracy and resolution. Exclusive to the 789 model are a 24 V loop power supply and a HART mode setting (which adds a 250-ohm resistor), making it the ideal tool for troubleshooting, calibrating, and documenting current loop applications in industrial environments. It also features Fluke Connect® compatibility for wireless data logging and sharing.
