Leak Detectors - Pfeiffer Vacuum

Leak detectors: the answer to all your leaks, no matter how big or small
Pfeiffer Vacuum leak detectors trace every leak. 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. From miniature electronic units right up to large-volume vessels, from media escaping from vacuum systems to gases entering them – the uses for leak detectors are as broad as the range of industrial products. The extensive range of Pfeiffer Vacuum leak detectors provides the answer for all these requirements.

Leak detectors for various requirements: portable, compact and stationary units
Our portable leak detectors are used both for mobile leak detection “on site”, such as company premises, as well as for worldwide service jobs in a variety of different locations. Our leak detectors stand out above all due to their high performance combined with low weight.

The compact leak detectors are used first and foremost for stationary applications to detect leaks and test for leak tightness. They are also portable thanks to a special leak detector cart. Compact leak detectors are used in widely ranging industries, from applications in heavy industry right up to clean room applications. In this latter case, the dry versions of the leak detectors are being used.

Stationary high-performance leak detectors are used where extremely short cycle times and fast cleanup of Helium background are required. Our leak detectors of the ASM 192 and ASM 1002 series are used in applications ranging from large-scale testing of electronic components for leak tightness up to highly sensitive applications in vacuum and medical technology or research and development.

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. These data can be used to improve production processes and successfully detect every leak.
