    The Fluke 789 Process Calibrator is the ultimate troubleshooting tool for electricians and instrumentation professionals, combining the functionality of a loop calibrator with the power of a digital multimeter.

    The Fluke 789 Multimeter and Process Calibrator is a combined Digital multimeter and current loop calibrator that gives the process technicians double the power in one handheld tool.

    The Fluke 789 has a 24 V loop supply for reducing the need to take a separate power supply when doing offline transmitter testing. And thanks to its built-in, selectable 250 ohm Hart® resistor, it also eliminates the need to carry a separate resistor for calibrating HART instruments with you. All this means that process technicians can now do a lot more while carrying a lot less.
