LACO offers both custom and standard leak testing system designs using the following leak testing methods:

• Helium Vacuum: 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: A manual method of sniffing a pressurized part to detect helium escaping a leak.
• Helium Accumulation: An automated method of capturing and accumulating helium in an enclosure surrounding a part pressurized with helium.
• Helium HATS: A patented automated method of capturing and accumulating helium in an enclosure (evacuated to partial vacuum) surrounding a part pressurized with helium.
• Air Testing: A variety of automated test methods using air as the test media for detecting leaks by pressure decay or mass flow.
• Multi-Gas Vacuum: An automated method using a tunable mass spectrometer where the part or test fixture is evacuated to full vacuum while the desired non-helium tracer gas is introduced to the opposite barrier of the part.
• Multi-Gas Sniffing: 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.
