Leak testing with detection gases such as helium
Find the smallest leaks
Non-toxic, odorless, and easy to trace – the noble gas helium has numerous advantages. This is why we have developed comprehensive and needs-based testing concepts using helium and other detection gases.
Helium only occurs in the ambient air in low concentrations and does not react with other gases. It can also be used regardless of temperature and volume changes.
The result: Quick tests in which even the smallest leaks are detected are possible. ZELTWANGER has expanded its expertise in this area and, with the ZEDcell and ZEDdetect, offers comprehensive, adaptable test systems for detection gas testing.
ZEDcell – the system for leak testing with detection gases
ZELTWANGER sees itself as more than a supplier of leak testing systems – it is a complete system partner that is constantly monitoring changing quality assurance requirements.
This is why we have developed the ZEDcell, a standardized, robot-controlled system which you can use to locate even the smallest leaks using the sniffer method. It can be easily adapted to your needs and integrated into your production lines.
ZEDdetect – vacuum test and accumulation method
With the ZEDdetect, we have developed a modular system for the vacuum and accumulation testing method. We configure the test chamber according to your requirements or the test method.
The advantages of the ZEDdetect
If you are looking for a system for leak testing with detection gases, please get in touch with our service team. We are happy to offer competent advice.
Test method with detection gases like helium
Depending on the application environment and requirements, three leak testing methods with detection gases, such as helium or hydrogen, are particularly suitable: The sniffer test, the accumulation test, and the integral vacuum test.
Here are the methods in more detail:
The leakage rates from individual tests demonstrate the precision of the method.
