Vacuum leak testing is required to accurately determine whether sealed vessels have leakage from external sources into their housing. Quantifying a detected leak allows for monitoring so that any degradation can be anticipated with the appropriate corrective action. This testing helps companies save costs associated with lost time and production incurred from repairing leaks after startup.
What do We Test?
We offer vacuum leak testing on any device or component that can be evacuated and where helium may be applied to the opposite side of the pressure boundary or across which a pressure differential of helium may be created where the opposite side of the pressure boundary is accessible for probing.
Applied Technical Services is an industry leader in vacuum leak testing services. Our qualified technicians utilize innovative technology in our ISO 9001:2015 registered laboratories to provide reliable solutions for your leak testing needs. Using the vacuum box method, we are capable of locating leaks as well as quantifying the rate of leakage in pressure vessels.
