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. The 787 starts with the Fluke-87 DMM you know and
trust, then adds ability to measure, source, and simulate DC loop current with 0.05%
accuracy and 1 micro-amp resolution. When you carry the ProcessMeter, you're ready
for any loop troubleshooting or calibration task. And since its dust- and
splash-resistant and EMI-shielded, the 787 can survive in your tool belt. The Fluke model
787 ProcessMeter should be in your tool box, see the Comparison
Chart and FAQ/Information page for more details.
