Request Information
The Ashcroft® 50 mm HPS high-purity pressure gauges with Reed Switch are ultrasonically cleaned to provide exceptional quality and reliability in ultra-high-purity gas delivery systems. Its stainless steel construction and wetted components are ideal for use with industrial gases in semiconductor and electronic manufacturing. The Reed Switch capability provides an additional safety feature through actuating an internal switch that triggers an alarm or a process condition change. This high-purity pressure gauge is an ideal choice for reducing installation costs and providing an added space reduction benefit.
