HIOKI RESISTANCE METER RM3548
High-precision Portable Resistance Meter Measures from µΩ to MΩ
Hioki DC resistance meters measure a broad range of resistance values at a high level of precision. The RM3548 is a high-precision, portable resistance meter capable of measuring resistance levels from microohms to megaohms, and is ideal for the testing and maintenance of large equipment, for example, measuring the winding and weld resistances in large motors and stators for hybrid and electric vehicles.
