Description

Universal Stainless Steel Bourdon Type Gauge: Many applications require pressure gauges, which must remain fully functional under extreme operating condition such as aggressive fluids under pressure or aggressive environments. In this case the materials used for the pressure gauges components must be selected with particular care. Micro high quality pressure gauges are built with stainless, chrome- nickel steels (i.e. S.S.316 or better). They can be used under all operational conditions, practically without limitations. Their concept combines sturdy design and high measuring accuracy. The pressure gauges are suitable for extreme measuring conditions. Variable designs and materials enable them to meet the requirements of virtually all-international pressure gauge standards. The gauges can be used for all liquids and gases used in processes except for those having a high viscosity, or which are liable to crystallized.
