Fluke 1587 FC Insulation Multimeter

The high-performance 2-in-1 insulation DMM

The Fluke 1587 FC Insulation Multimeters combine a digital insulation tester with a full-featured, true-rms digital multimeter in a single compact, handheld unit, which provides maximum versatility for both troubleshooting and preventative maintenance.

The Fluke 1587 FC Insulation Multimeter adds four powerful new diagnostic functions through the Fluke Connect® Measurements app:

PI/DAR timed ratio tests with TrendIt™ graphs identifies moisture and contaminated insulation problems faster
Memory storage through Fluke Connect eliminates writing down results, reduces errors and saves data for historical tracking over time
Temperature Compensation through app for establishing accurate baselines and relevant historical comparisons
Historical tracking and trending of assets identifies degradation over time, allows real-time decisions to be made in the field with Fluke Connect® Assets
