Description

These Micro pressure gauges are suitable for aggressive environments as they are housed in a weather proof enclosure so that the copper alloy internals are not damaged and gauges remain fully functional under such extreme conditions. They can be used for all liquids and gases under pressure, except for those which attack copper alloys and those having a high viscosity, or liable to crystallised i.e. which can damage pressure measuring element.
