The 789 is the ultimate troubleshooting tool for electricians and instrumentation professionals, combining the functionality of a loop calibrator with the power of a digital multimeter.
Safety rated multimeters with mA source. Now process technicians can do a lot more while carrying a lot less. The ultimate loop calibration multimeter - the Fluke 789 ProcessMeter. The Fluke 789 ProcessMeter was the first tool to combine a loop calibrator with a DMM to give process technicians double the power in one tool.
