Brand : Fluke
Model : 787B
Product Description
The Fluke 787B ProcessMeter™ doubles your troubleshooting capabilities by combining the power of a safety rated digital multimeter and mA loop calibrator into a single, compact test tool. Based on the trusted measurement capabilities of the Fluke 87V meter, the 787B adds the ability to measure, source and simulate mA with the accuracy and resolution you would expect from a Fluke mA loop calibrator, giving you the ideal tool for troubleshooting and calibrating current loop applications.
With Fluke Connect® mobile app and desktop software compatibility, technicians can wirelessly monitor, log, and share data from the field with their team anytime, from anywhere.* If you’re looking for even more troubleshooting power, the Fluke 789 ProcessMeter™ offers technicians even more flexibility, and even includes a built-in 24 V loop power supply.
