Fluke originally combined a 4-20 mA loop calibrator and a multimeter to give process technicians double the power in one tool, the original Fluke 787. Now Fluke made it even better - the ultimate loop calibration multimeter - the Fluke 789 ProcessMeter. The Fluke 789 has a display that's not only twice as large, but also twice as bright with two levels of backlighting. With its built-in, selectable 250 ohm HART® resistor, it eliminates the need to carry a separate resistor with you and behaves when connecting to a smart transmitter. Now process calibration technicians can do a lot more while carrying a lot less.
