Rave Scientific offer the Pfeiffer ASM 340 and ASM 310 Helium leak detectors. The Pfeiffer Helium leak detectors are portable and are used both for mobile leak detection “on site”, such as company premises, as well as for worldwide service jobs and can be used in a variety of different locations. The Pfeiffer leak detectors stand out above all due to their high performance combined with low weight. Compact leak detectors are used first and foremost for stationary applications to detect leaks and test for leak tightness and range in applications from industry right up to semi-conductor clean room applications. In this latter case, the dry version ASM 310 helium leak detectors are being used.
Leak detection with the test gas helium is safe, quantitative and 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, a 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.
