How to test helium leaks?
The testing method with tracer gas guarantees the maximum sensitivity and the possibility to identify extremely low leaks, also for big volumes and in any environmental condition. Our helium leak test systems in accumulation chambers are capable of testing leaks with thresholds in the range of 10 -2 - 10 -4 SCC/sec.
What is a helium test machine?
Machine designed to test complete cells before electrolyte filling and sealing. The same type of machine can be used to check finished cells after filling and sealing, in particular using the helium as tracer gas when it has been filled in the cell with the electrolyte.

What are the new leak test requirements for battery cells?
ty and performance.leak test for battery cellsWith HEV/EV technology comes new leak test requirements for the automotive industry: each single battery cell must be protected, reliab y, against any penetration of humidity and air. The MARPOSS helium vacuum
How helium is used in a bombing cell?
The tested cell is firstly introduced into the bombing chamber, filled with high pressure Helium. In presence of a sealing defect in the housing, the helium will enter the cell. The cell is then moved to the vacuum chamber, where the helium will be free to exit from the cell through the same sealing defect.
How does a helium tracing machine work?
The same type of machine can be used to check finished cells after filling and sealing, in particular using the helium as tracer gas when it has been filled in the cell with the electrolyte. The machine provides two vacuum chambers, with automatic opening and closing, assembled on a welded and painted steel frame with movable panels.
