The Pfeiffer Adixen ASM 182/192 series includes the latest evolutions of Adixen leak detectors, of which thousands are utilized in successful daily operation throughout the world in various applications and industries, including the automotive, chemical and mechanical, and electrical, electronics and packaging industries. A standout product of this series is the Adixen ASM 182 TD+ helium leak detector, utilized extensively in quality control purposes and maintenance of semiconductor processing systems, as well as quality control of vacuum components. Additionally, it is utilized as a blister-testing appliance within the pharmaceutical industry. This brand of Pfeiffer Adixen leak detectors offers several unique features, among them high sensitivity [5 x 10^(-12) mbar l/s], in addition to rapid response time while activated in spraying mode.

The Adixen ASM 182 TD+ leak detector is extremely flexible and user-friendly, with an emphasis on operational durability and ease-of-access. Automatic operation is provided throughout a vast range of processes, including atmospheric sniffer testing and refinement of extended gas lines and tubing. The ASM 182 TD+ mechanism likewise features a range of distinct operating modes, including gross leak mode and ultra-sensitive vacuum fine leak mode. Readily available basic functions, combined digital and analog display, and a range of advanced functions are also included for user convenience.


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.

Utilizing the beneficial qualities of helium, a Helium Leak Detector pumps molecules of the gas into the device's analyser cell through the use of vacuum pumps. The analyser cell works on the principle of mass spectroscopy and measures the gas's partial pressure, displayed on the device's spectrometer. A higher reading indicates that a leak may be present, as represented by the quantity and concentration of helium molecules that have passed through a given space, as analysed by the device. The leak detector converts this partial pressure of molecules into a flow rate. Helium leak detectors are known to be extremely precise and exhibit unparalleled accuracy in detecting leaks.
