RM3548 - HIOKI Portable Micro-Ohmmeter 1A Output

High-precision portable resistance meter measures from μΩ to MΩ

Basic accuracy: 0.02%, Max. resolution: 0.1 μΩ, Max. measurable current: 1 A Measure from 0.0 µΩ (@ 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.
