A leak-detection solution for helium and hydrogen

| By Chemical Engineering

Screen Shot 2016-03-25 at 8.15.17 AMThe ASI 35 modular leak-detection system is especially suited for use with tracer gases, such as helium and hydrogen, in integral and localizing test procedures, or a combination of both, with minimum signal background and crosstalk, providing for fast overall cycle times, reportedly as short as 1 s. The modular design of the ASI 35 minimizes space requirements and simplifies integration options — only two cables are needed to connect the vacuum and electronic modules. The ASI 35 features a low-maintenance turbo pump for high helium pumping speeds and dual independent filaments. The leak detector is designed for working conditions in ambient temperatures up to 45°C. — Pfeiffer Vacuum, Nashua, N.H.
