The Fluke 789 ProcessMeter is the ultimate troubleshooting tool for electricians and instrumentation professionals. It combines the functionality of a loop calibrator with the power of a digital multimeter, and the wireless capabilities of Fluke Connect connectivity with optional IR3000FC module. The 789 has a display that's not only twice as large as the Fluke 787B, but also twice as bright with two levels of backlighting. And its built-in, selectable 250 ohm HART® resistor eliminates the need to carry a separate resistor.

The 789 also has a 24-Volt loop supply, which reduces the need to carry a separate power supply when doing offline transmitter testing. You can add an optional temperature measurement module and the wireless data logging capabilities of the Fluke Connect™ mobile app to log data wirelessly to your smart phone and review it from a remote location. So now process technicians can do a lot more while carrying a lot less.
