Hydrogen fuel cells, components and systems require a high degree of leak tightness for both performance and safety reasons. Both hydrogen and helium can be used as tracer gas implementing the sniffing and the vacuum techniques. Select from a product category below.
Helium Vacuum (HV): An automated method where the test part or test fixture is evacuated to full vacuum while helium is introduced to the opposite barrier of the part.
Helium Sniffing (HS): A manual method of sniffing a pressurized part to detect helium escaping a leak.
Multi-Gas Sniffing (MS): A manual method of sniffing a pressurized part using a variety of instruments specifically designed for non-helium tracer gases such as refrigerants, hydrogen and SF6.
