Used ALCATEL / ADIXEN / PFEIFFER ASM 180 TD #9253634 for sale

ALCATEL / ADIXEN / PFEIFFER ASM 180 TD is a high-performance, instrument level leak detector specifically designed to detect and quantify low levels of ultra-high vacuum equipment leaks. ADIXEN ASM 180 TD is equipped with a digital thermocompensated Pirani gauge with a fast vacuum control mechanism allowing the sensitivity control to be adjusted in order to set the detectable leak rate. The technology behind particle detection is mass spectrometry, which is based on detecting particles based on their masses relative to molecules of known masses. It works by passing a vacuumized gas, typically argon or helium, through a sample chamber. The gas is ionized, and a high-powered electric field accelerates the ions towards a detector. The detector differentiates between particles of different mass-to-charge ratios and reports the relative amount of each. ALCATEL ASM 180TD utilizes a combination of technologies to detect ultra-high vacuum system leaks. It's equipped with a double head ionization gauge mated to a venturi to maintain a positive pressure differential between the sample chamber and the vessel under test (VUT). This pressure differential enhances the sensitivity of the leak detection unit by allowing higher amounts of vacuum pumps to exhaust through the machine. The detector also features a dual leak rate output, which allows users to set the sensitivity threshold, thus enabling better leak rate control. The tool also features an auxiliary calibration port and a venturi-controlled manual pump which provides user-friendly operation. The digital thermocompensated Pirani gauge includes a thermal set-point controller, a capacitance manometer, a heated cold-cathode ion gauge, and a hot-cathode ion gauge. It is designed to monitor absolute pressure levels of ultra-high vacuum systems down to 10-13 mBarr. The gauge also performs a temperature compensation feature which ensures accuracy regardless of fluctuations in ambient temperature. ALCATEL ASM 180 TD is designed as a mobile unit, mounted in an ergonomic carrying case for easy portability. It is lightweight and has a wealth of other features, including an intuitive user interface, low power consumption, USB port for maintenance and software upgrade, an alarm signal for user notification, and an automated leak rate output cycle. It is designed to operate in laboratory and field environments alike, helping to quickly and accurately diagnose and repair pressure and vacuum gas leaks.
