Description
PRDR.W is an all-stainless-steel pressure gauge with a laser-welded case for excellent leak tightness. Safety features include a vent valve and a blow-out device. It is available with a SUS304 or SUS316 case and a SUS316L process connection, covering ranges from 0–0.6 kgf/cm² to 0–1600 kgf/cm². Accuracy is up to ±1.0% of full scale for 4-inch and 6-inch models. Designed for petrochemical plants, power engineering, water treatment, and other demanding industrial applications, it supports glycerine or silicone-oil filling and bottom, back, or flange mounting. Its specifications are comparable to WIKA 232.50/233.50.
