Diaphragm Pressure Gauge

The diaphragm pressure gauge uses a diaphragm as the sensitive element to measure low-pressure and negative-pressure media. It is suitable for non-corrosive media compatible with copper alloys and non-explosive gases, and is widely used in boiler ventilation, gas pipelines, combustion equipment, and other similar applications.
