2.5" Low Pressure Gauge -10~80 cmH2O U-Clamp Mount Bellows Manometer 316 SS Case Capsule Pressure Gauge
Description
Low pressure gauges have a very sensitive mechanism consisting of two corrugated discs, each made of brass or stainless steel, that are fused together to create a circular capsule. The slightest changes in pressure cause the capsule to expand or contract; a pinion movement mechanism transfers this motion to the indicator.
Applications
Low pressure gauge for applications in a controlled environment
Ideal for measuring pressure, vacuum in medical, environmental, and laboratory applications for content and filter monitoring
For gaseous, dry and non-aggresive media
Special features
Front zero adjustment
Special connections on request
Scale ranges from 0/10 InWC (25 mbar)
