Multimeter and Process Calibrator

Based on the trusted Fluke 87 DMM, the 787 adds the ability to measure, source, and simulate dc loop current with 0.05% accuracy and 1 microamp resolution.


The Fluke 787 ProcessMeter™ puts a complete troubleshooting solution in the palm of your hand. Get in touch with more information, faster and easier with the newest member of the Fluke 80 Series, the 787 ProcessMeter. The 787 gives you the measurement capabilities you expect from our rugged, reliable DMMs plus the ability to source, simulate, or measure dc current with 1 microamp resolution and accuracy of 0.05%. Put it all together and you have the ideal tool for troubleshooting and calibrating current loop applications. So if you're tired of always tracking down a calibrator, lugging around two tools and switching back and forth, get the single best solution for doubling your power. The 787 ProcessMeter from Fluke.Here's the power the 787 ProcessMeter™ puts into your hands.
