HIOKI RESISTANCE METER RM3545A

New Heights in 100% Inspection.
Market leading precision tests for testing every weld or connection on your production line.

As electric mobility gains popularity, manufacturers are developing components for higher currents and voltages. Since even minuscule amounts of resistance can have a significant impact on energy efficiency and safety, more accurate quality control focusing on resistance is required. The Resistance Meter RM3545A facilitates accurate resistance measurements and is suitable for diverse applications in development and production lines.

Manage connection quality in welded materials and other parts quantitatively: Quantitatively verify weld quality and weld methods in EV power cables and other parts

Use readings as indicators for thermal design and energy management: Use accurate resistance measurements to simulate heat loss and energy efficiency

Boost productivity by embedding the instrument in automatic test equipment: Embed the instrument in a system without needing to worry about wiring resistance or contact resistance. The instrument is ideal for use in high-speed 100% inspections
