    Double Your Power

    The Fluke 787 was the first tool to combine a DMM and a loop calibrator to give process technicians double the power in one tool. Now it’s even better, the range is extended with the Fluke 789 – the ultimate loop calibration multimeter. The Fluke 789 has a 24-Volt loop supply reducing the need for taking a separate power supply when doing offline transmitter testing. And with its built-in, selectable 250-Ohm Hart® resistor, it also eliminates the need to carry a separate resistor with you. Now process technicians can do a lot more while carrying a lot less.

    Includes:

    • ProcessMeter
    • AC175 Alligator Clips
    • Four AA 1.5 V alkaline battery (installed)
    • TL71 Safety-Designed Test lead Set
