Helium Recovery |
Automatic recycling system, helium recovery rate≥98% |
Basic Working Principle
According to the basic principles of helium leak detection, helium as a tracer gas, the workpiece will be filled with helium in the vacuum chamber, and then through a helium leak detector leak can quickly and accurately determine the accuracy of the workpiece’s leakage.
