HIOKI RESISTANCE METER RM3548
3-Range, 250 to 1000V Analog Insulation Resistance Tester with Continuity Check
Hioki insulation resistance testers or megohmmeters feature all-in-one designs including built-in rugged cases and test lead storage compartments. The 3490 is a 3-range, 250/500/1000V analog insulation resistance meter with efficient functions and features to help shorten work time associated with field insulation testing.
Overview
- 0.02 % basic accuracy, 0.1 μΩ max. resolution, 1 A max. testing current, 1A max. testing current
- Measure from 0.0 µΩ (testing current 1 A) to 3.5 MΩ
- Easily record up to 1,000 data points in memory simply by applying the instrument’s probes
- Smoothly capture temperature-rise test data using interval measurement
- Portable design is ideal for maintenance and testing of large equipment
