Schaffer diaphragm gauges are used for the measurement of pressure with either gas or liquid. The fluids can be corrosive, polluted or highly viscous. For the measurement of highly viscous or crystallizing process fluids, a flange is used. A schaffer gauge is used for the measurement of both vacuum and pressure.
