We provide TOTAL SOLUTION of Helium Leak Tester and its Recovery System
From the first development of Helium Leak Tester in 2003, Logics Corporation has been challenging to innovate a new Helium Leak Tester. Helium Leak Tester is the best method to detect micro leakage of airtight parts. We also have been developing high efficient Helium Recovery System since 2013.
Recover high cost Helium resource and its reuse!
Helium is limited resource. Recently, Helium gas price is rising every year and production cost rises accordingly. It is a challenge to reuse this limited Helium resource for necessary Helium Leak Test and reduce production running cost.
