12-station relay charging evacuation tester, EV relay helium leak test equipment, automotive relay air tightness detector, multi-station vacuum leak bench, helium recovery sealing test machine

This integrated 12-station testing unit adopts fully independent vacuum and gas circuit for each position to eliminate cross-test interference. It automatically completes workpiece clamping, pre-evacuation, quantitative helium filling, micro-leak scanning and gas recovery in one cycle. Equipped with industrial touch HMI and pre-stored standard test programs matching ISO20485 and IEC 60255, all test data carries time stamps and can generate standardized reports recognized by global automotive OEM audit institutions.

Besides relay helium leak testing equipment, HeJin supplies a full lineup of auto parts reliability testers.
