The Ashcroft 50 mm HPS high-purity pressure gauge with Reed Switch is ultrasonically cleaned to provide reliability in ultra-high purity gas delivery systems. 

The Reed Switch capability provides an additional safety feature through actuating an internal switch that triggers an alarm or a process condition change.

The gauge features stainless-steel construction and wetted components that are used with industrial gases in semiconductor and electronic manufacturing. It’s Helium leak tested to 1 x 10^-8 scc/s, cleaned in class 10,000 cleanroom and packed in a Polyethylene-sealed bag after nitrogen gas flushing.
