Conductor Resistance Evaluation System (AMR)

Efficient evaluation of the reliability of connectors

This system enables continuous measurement of micro resistance values of solder joints and conductor parts of connector contacts in low-temperature and high-temperature thermal cycle environments. Automatic measurement, data storage, and data processing are operated systematically with a computer. Featuring data graphs, compatibility with spreadsheet software, and data processing via LAN, this system enables more accurate and efficient connection reliability evaluation.
