Hioki RM3548-50 Resistance Meter

Hioki RM3548-50 Resistance Meter

The Hioki RM3548-50 is a wide-range precision resistance meter measuring from 3mΩ to 3MΩ across ten ranges using the DC four-terminal method, which eliminates lead-resistance error. With ±0.020% accuracy, built-in temperature measurement and Bluetooth data transfer, it is well suited to EV maintenance, motor inspection, aircraft overhaul and contact-resistance work.

Key Features

• DC four-terminal resistance measurement, 3mΩ to 3MΩ in 10 ranges
• High accuracy: ±0.020% rdg. ±0.007% f.s.
• Temperature measurement -10.0°C to 99.9°C (thermistor)
• Memory for up to 1,000 manual/auto or 6,000 interval readings
• Comparator with PASS/WARNING/FAIL judgement
• USB and Bluetooth (with the optional Z3210 adapter), Excel direct input
• Circuit protection up to 42.4V peak AC / 60V DC
• LR6 alkaline battery ×8 or HR6 NiMH ×8, approx. 10 hours operation
