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 its even better, the range
is extended with the new 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 Hartź 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. |
