The WIKA 232.25 pressure gauge is a bourdon tube style process gauges that include a hinged ring for easy access to the adjustable pointer. Designed specifically for use in pressure monitoring panels, these gauges are available in ranges from vacuum to 20,000 psi. The 232.25 is ideal for many applications within the process industry such as chemical/petrochemical, power stations, mining, on and offshore, environmental technology, mechanical engineering and plant construction. Both gauges are suitable for corrosive environments and gaseous or liquid media that will not obstruct the pressure system.

The WIKA 232.25 pressure gauge is designed to ASME B40.100 standards. Each gauge features a durable aluminum case and ring that provides weather tight NEMA 3 / IP54 protection. Available with 4 1/2 or 6in dials, the 232.25 includes a lower back pressure connection to facilitate panel mounting. The gauge is unfilled.
