Helium Leak Detection

Leak detectors: the answer to all your leaks, no matter how big or small.

No leak is too small or too big to escape our leak detectors. It doesn’t matter whether you are looking for water, oil, fuel, refrigerant, gas, steam, air or vacuum leaks.

Leak detection with the test gas Helium: Safe. Quantitative. Repeatable.

Helium leak detectors are the ideal solution for leak detection and leak-tightness testing under vacuum. The test gas Helium is safe and a small, light molecule which is suitable for detecting micro leaks. The detection range of Helium in vacuum tests lies between 10-2 and 10-13 Pa · m3/s. Helium leak detection is extremely accurate, quantitative and repeatable. Fast cycle times are a further advantage.

Manual sniffing or spraying is often the easiest way to detect a leak with Helium. But it is also possible to use automatic leak detection solutions which are independent of the operator and provide a considerably higher detecting speed. The integral leak detection is designed to achieve pre-defined quality and component throughput levels.

The use of test gas leak detection methods has the bonus of delivering extra data compared to traditional leak detection methods such as bubble testing or pressure drop methods. This data can be used to improve production processes and successfully detect every leak.
