Used ALCATEL / ADIXEN / PFEIFFER ASM 180 #9259165 for sale

ALCATEL / ADIXEN / PFEIFFER ASM 180 is a high-precision leak detector capable of detecting trace levels of helium, hydrogen, and other gases. It is a vacuum system that uses thermal conductivity of a particular gas to detect traces in a gas mixture. ADIXEN ASM 180 is suitable for numerous leak testing applications requiring high precision, including sealed devices in air conditioning systems, automotive airbags, and precision instruments. It is also used in the electronics industry for hermetic sealing of integrated circuits and chip packages. ALCATEL ASM 180 features a modular design for multiple configurations, allowing users to select the best combination of components for their specific requirements. Its main components include an analytical cell for measuring gas concentrations, an automatic calibration chamber, a rough/fine pumping station (RFP/FPP), two mass flow controllers, and an integrated microprocessor control unit (MCU). The analytical cell is the heart of ASM 180. It is composed of four stainless-steel housing elements and is filled with a noble gas atmosphere such as helium or hydrogen. When a sample is introduced into the chamber, the gases attain an equilibrium concentration within the cell by diffusion. The concentration is then measured using a thermal sensor. This data is sent to the MCU that processes it with highly accurate algorithms to detect leaks. The RFP/FPP is used to maintain optimal operating conditions within the analytical cell. It is equipped with an active mechanical backing pump and an RFP pump to evacuate the sample chamber and reach the desired base pressure. The two mass flow controllers provide additional gas control functions, such as selecting the test gas, preconditioning the sample chamber, and automatically detecting and correcting any fluctuations in base pressure within the cell. PFEIFFER ASM 180 can be operated from either the remote user interface or directly from the control unit. It provides a range of pre-set parameters such as leak test protocol, sample concentration level,etc. which can be adjusted as per the user's requirements. In summary, ALCATEL / ADIXEN / PFEIFFER ASM 180 is an advanced precision leak detector, specifically designed to detect trace levels of helium and hydrogen in a gas mixture. It is highly reliable, accurate, and easy-to-operate and provides the user flexibility and control over their leak testing requirements.
