Double Your Power

A maintenance and calibration tool that will be at home in every instrumentation technician's tool box, the Fluke 787 ProcessMeter™ combines a DMM and a Loop Calibrator in one rugged, handheld tool, for about what you would expect to pay for a loop calibrator alone. 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.
