Description

The PRS is a stainless steel case pressure gauge designed for general industrial applications, featuring brass or chrome-plated brass process connections suitable for non-corrosive gas and liquid media. With configurable ranges from 0–1 kg/cm² up to 0–1000 kg/cm² and dial sizes from 1.5″ to 4″, it offers accuracy up to ±1.6% F.S. The gauge can be supplied dry, glycerine-filled, or silicone-filled for improved vibration resistance and is available in multiple mounting options including bottom, back, center back, flange, and U-clamp. This makes the PRS ideal for pumps, compressors, hydraulic systems, and general indoor/outdoor pipeline monitoring.
