At the ComVac, Pfeiffer Vacuum is presenting the ASI 35, a leak detector that is ideal for mechanical engineers, integrators and end users. It combines high performance, reliability and repeatability with extremely short cycle times. At the same time it provides maximum flexibility. It can use both helium and hydrogen as tracer gases. The leak detector is designed for sophisticated testing tasks with miniscule background signals and enables short overall throughput times. In addition, the sturdy iridium filaments ensure a long lifetime.
