Stainless steel diaphragm pressure gauges are suitable for measuring the pressure of liquids and gases with certain corrosiveness, high viscosity, and no crystallization.

Stainless steel diaphragm pressure gauges are mainly used for measuring small pressures of gases and liquids in the chemical, petroleum, and textile industries, especially for measuring small pressures of highly corrosive and viscous media (non solidifying and non crystalline). And different materials of membranes can be selected according to different measurement media.
