Ashcroft 1127 & 1128 Differential Pressure Gauges

Ashcroft 1127 & 1128 Differential Pressure Gauges

Industrial Pressure Measurement & Monitoring

Ashcroft Instruments 1127 & 1128 differential pressure gauges display the difference from two separate inputs on one dial indicator.

When the process is corrosive to gauges with bronze/brass wetted parts, an alternative was to isolate the gauge from the process with capillary and isolators or diaphragm seals, Ashcroft Instruments 1127 or 1128 differential pressure gauges can be used if the process is compatible with 316 Stainless Steel.
