Ashcroft 1133 Differential Pressure Gauges

Industrial Pressure Measurement & Monitoring

Ashcroft Instruments 1133 differential pressure gauge uses a convoluted diaphragm to sense low inches of water differentials while ensuring no migration of the process media and has maximum static pressures for ranges of 5 IWD and below is 45 psi and 500 psi for all other ranges.

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).
