Helium Leak Detector is one of the most precise leak testing methods that available, it is essential for ensuring product quality and safety.
Gadro’s helium leak detector is a compact, portable and precision device with high sensitivity, fast response and easy operation. Engineers use it for both vacuum and sniffer testing.
Till now, many GHLD have been kept in maintenance stations/R&D labs for fast pinpoint fault analysis and on-site repairs, it pairs with helium recovery system to empower intelligent production lines efficiently and economically.
