FLUKE-789产品概述
Double your power.
The Fluke 787 ProcessMeter was the first tool to combine a loop calibrato with a DMM to give process technicians
double the power in one tool. Now it’s even better – the ultimate loop calibration multimeter – the Fluke 789 ProcessMeter. The 789 has a display that’s not only twice as large, but also twice as bright with two levels of backlighting. And with its built-in, selectable 250 ohm HART? resistor, it eliminates the need to carry a separate resistor with you. Now process technicians can do a lot more while carrying a lot less.
