Description
The PRSM is a low-pressure capsule gauge featuring a stainless-steel case and designed for gaseous media compatible with copper alloy components (excluding liquids). It offers measuring ranges from 0–300 mmAq to 0–5000 mmAq, including vacuum and compound options. With chromium-plated copper wetted parts and zero-point adjustment capability, the gauge is available in 2.5″, 3″, and 4″ dial sizes, using acrylic windows for 2.5″ and glass windows for 3″ and 4″. The PRSM is ideal for HVAC systems, cleanrooms, laboratories, medical gas supply, and general low-pressure monitoring applications, combining the durability of a stainless-steel case with the sensitivity of a capsule gauge.
