Pfeiffer ASM 390 Mobile Helium Leak Detector with ACP 40 Dry Scroll Pump and SplitFlow 80, ASM390, 2000034669 / CSGB01G2MM9A Pfeiffer ASM 390 Overview: The ASM 390 is optimized for quick and accurate leak detection in all ranges of measurement. The new ASM 390 Mobile Helium Leak Detector has a dry backing pump with a backing capacity of 35 m^3/h. The compact design of the ASM mobile leak detector allows for high maneuverability without sacrificing performance. A large, fully-rotating color touch screen display is included within this product, with the option for detachment without the requirement of tools. An integrated toolbox for storage of accessories is likewise included within the ASM 390 product package. The CSGB01G2MM9A configuration of Pfeiffer ASM 390 comes with a 37 pin I/O interface to allow for control options through PCs/PLCs. Pfeiffer ASM 390 Features: Dry and clean pump with high backing capacity (35 m3/h) Fast time to test: unrivalled performances from small to large volumes High maneuverability and compact design Large color touch screen, fully rotatable and detachable without any tool Integrated toolbox for storage of accessories Fully configurable I/O interface (37 pins D-Sub) to allow control through PCs/PLCs A Brief Description of the Science and Processes Involved in Helium Leak Detection: Leak detection utilizing helium has a complex history dating back to the first half of the twentieth century and is used in a variety of processes and industries. Helium is used as the preferred tracer gas for eliminating leaks for a variety of reasons, including its non-flammability, non-toxicity, and inexpensiveness relative to other gases. Likewise, its inert state and small atomic size (helium has an atomic mass unit of 4 - second only to hydrogen, which has an AMU of 2) allows the gas to pass through leaks with ease. Unlike hydrogen however, helium is stable and non-explosive, providing a better alternative to be used in leak detection processes.
