Hioki Resistance Meter RM3545 Series

Wide Range 10 mΩ to 1000 MΩ DC Resistance Testers with Multiplexer Option for High-speed Multi-point Testing

Hioki DC resistance testers measure a broad range of resistance values at a high level of precision. The RM3545 series are super-high-precision, multichannel-capable resistance meters that meet applications in advanced research and production for testing winding resistance of motors and transformers; contact resistance of power relays, switches, and connectors; and resistance of signal relays and magnetic parts.

RM3545: Basic model
RM3545-01: with GP-IB
RM3545-02: Multiplexer installable
