Description

The PRDR.W is a fully stainless steel pressure gauge formed with seamless laser welding, providing excellent leak prevention along with enhanced safety features such as a vent valve and blow-out back. Available in 304 or 316 stainless steel housings with 316L process connections, it supports ranges from 0–0.6 kg/cm² up to 1600 kg/cm², offering accuracy up to ±1.0% F.S. for 4″ and 6″ models. Designed for harsh environments such as petrochemical plants, power engineering, and wastewater treatment, it supports glycerine or silicone filling and multiple mounting options including bottom, back, and flange types. Its specifications match those of WIKA 232.50/233.50, making it a reliable alternative to major international brands.
