High-purity pressure gage with reed switch

| By Gerald Ondrey

The 50-mm HPS high-purity pressure gage with reed switch (photo) is ultrasonically cleaned to provide exceptional quality and 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 gage features stainless-steel construction and wetted components that are ideal for use with industrial gases in semiconductor and electronic manufacturing. It is helium leak tested to 1 × 10 –8 std. mL3/s, cleaned in class 10,000 cleanroom and packed in a polyethylene-sealed bag after nitrogen gas flushing. — Ashcroft Inc., Stratford, Conn.
