Ashcroft 1131 Differential Pressure Gauges

Ashcroft 1131 Differential Pressure Gauges

Industrial Pressure Measurement & Monitoring

Ashcroft Instruments 1131 differential pressure gauge is used for applications where migration of the process media is not permissible and has a rolling diaphragm design to separate the high and low-pressure ports to isolate the media and can see up to 3,000 psi static pressures. 

A choice of body materials is available in aluminium, brass and Stainless Steel; with Buna, Viton or EPDM seals (other wetted parts include Stainless Steel, Teflon and ceramic).
