RCC Electronics offers HIOKI RM3542-series high-speed resistance meters and the RM3548 portable micro-ohmmeter for stable low-resistance measurement from production benches to field maintenance work.
Micro-ohmmeters help teams verify contact resistance, connection quality, winding resistance, bonding, busbars, shunts, switches, relays, and other low-resistance paths where small changes can matter. RCC’s HIOKI Micro-ohmmeter category focuses on RM3542 bench units and the RM3548 portable meter.
Use high-speed, high-stability bench resistance meters for repeatable inspection and quality-control workflows.
Use a portable micro-ohmmeter when low-resistance measurement is required outside the lab or production bench.
Select the GP-IB model where the test station needs instrument control or production-line integration.
The RCC category lists four HIOKI low-resistance measurement products: three RM3542-series bench models and one RM3548 portable micro-ohmmeter.
HIOKI Micro-ohmmeter, 100 mA test current
HIOKI Micro-ohmmeter, 100 mA test current
HIOKI Micro-ohmmeter with GP-IB interface
HIOKI Portable Micro-ohmmeter, 1A output
