The stainless steel 23X.30 4.5" safety case pressure gauge is built to provide reliable pressure readings in demanding applications such as those in the/refining, chemical processing, power generation, oil exploration, and environmental technology industries.

With pressure ranges up to 20,000 PSI and an accuracy of ±1.0% of span (ASME Grade 1A), it is suitable for corrosive environments and gaseous or liquid media that will not obstruct the pressure system.

The design meets American Petroleum Institute (API) and industry-specific specifications and does much more. The stainless steel gauge on the model 23X.30 4.5" features an ASME/ANSI-approved solid front/ blow back safety case while the all-stainless steel construction allows for excellent load-cycle stability and shock resistance.

The Model 23X.30 4.5" safety case pressure gauge is just one of the "30 series" of bourdon tube pressure gauges from WIKA. Other case sizes within this series include the 2.5", 4", and 6".
