Description

The PRSSM.TU is a capsule-type low-pressure gauge designed for dry and aggressive gaseous media, featuring 316L stainless-steel wetted parts and a 304/316 stainless-steel case for enhanced durability in harsh environments. It offers extremely low-pressure ranges starting from 0.5 kPa (6″ dial) up to 100 kPa, with accuracy options of ±2.5%, ±1.6%, or ±1.0% F.S. The gauge is available in non-filled or silicone oil–filled versions to improve resistance to vibration and dynamic pressure loads. Additional features include IP65 protection, a front zero adjustment mechanism, and multiple mounting options (bottom, back, flange, or U-clamp). This makes the PRSSM.TU ideal for corrosive gases, laboratories, process monitoring, and HVAC low-pressure applications.
