    Now compatible with Fluke Connect™ App

    The Fluke 789 ProcessMeter is the ultimate troubleshooting tool for electricians and instrumentation professionals, combining the functionality of a loop calibrator with the power of a digital multimeter. By equipping the 789 with a temperature measurement module and the wireless data logging capabilities of Fluke Connect™ with ShareLive™ video call (sold separately), process technicians can now do a lot more while carrying a lot less. And with its built-in, selectable 250 ohm HART® resistor, it eliminates the need to carry a separate resistor with you.

    Specific Fluke Connect capabilities
    The Fluke 789 ProcessMeter is now compatible with the Fluke Connect mobile app. The new Fluke ir3000 FC Connector (sold separately) allows you to live stream and capture data from the main display of your Fluke 789 to your smart phone. Store main screen display data to FlukeCloud storage for access by other team members.
