- 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.
The RM3545A-1 is the successor from RM3545, and the RM3545A-2 is the successor from RM3545-02.
