Note: 1. Users may also choose other general-purpose pressure gauges, and can negotiate with our company during the ordering process.

2. The connection method for the pressure gauge and diaphragm assembly can also be selected in other forms; please consult with our company when placing an order.

◆ Diaphragm meter corrosion resistance

The corrosion resistance of diaphragm gauges can be ensured by appropriately selecting the materials of the diaphragm, flange, and sealing ring in contact with the measuring medium.

Diaphragm Material: 316, 316L

Flange Material: 316, 316L

Seal Material: Silicone Rubber

◆ Selection of Sealing Fluid

To ensure the reliability and safety of using the sanitation-type diaphragm, select the appropriate sealing fluid based on different applications.
