Hioki RM3545 Resistance Meter

Hioki RM3545 Resistance Meter

Introducing the Hioki RM3545 Resistance Meter – the ultimate solution for high-precision and multi-point resistance testing. With a wide range of 10 mΩ to 1000 MΩ, the RM3545 offers super-high-precision, multichannel-capable resistance measurements for advanced research and production applications.

Versatile Applications of the RM3545

This resistance meter is perfect for testing winding resistance of motors and transformers, contact resistance of power relays, switches, and connectors, and resistance of signal relays and magnetic parts. With a 0.006% basic accuracy, 0.01 μΩ max. resolution, and 1A max. testing current, the RM3545 delivers reliable and accurate measurements every time.

High-Precision and Reliable Measurements

The RM3545 also features a multiplexer unit option, providing 20-channels of 4-terminal measurements for a complete assessment of multi-point signals. Its low-power resistance measurement with an open voltage not exceeding 20 mV makes it ideal for measuring contact resistance from the 0.1μΩ to 1kΩ range.

Multiplexer Unit Option for Multi-Point Signals

The Hioki RM3545 is built-in with an Offset Voltage Compensation (OVC) function to correct for the effects of electromagnetic force (EMF), making it perfect for measuring low resistance of the welding points of busbars.

Offset Voltage Compensation (OVC) Function

The RM3545 allows you to identify defective welding that causes increased resistance at junctions, causing greater heat/energy loss during charging and recharging. You can even improve productivity by increasing the number of inspection channels, up to 132 channels, with the SW1001/SW1002 switch mainframes.
