Double your power.

The Fluke 787 ProcessMeter was the
first tool to combine a loop calibrator
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.
