FLUKE 789

The Fluke 789 Process Meter is the ultimate troubleshooting tool for electricians and instrumentation professionals, combining the functionality of a loop calibrator with the power of a digital multimeter. By also equipping the 789 with a temperature measurement module and built-in, selectable 250 ohm HART® resistor process technicians can now do a lot more with a single instrument.
