Diaphragm pressure controllers are suitable for measuring the pressure or negative pressure of various liquid media with a certain degree of corrosiveness, viscous media and non-crystallization or non-solidification. According to the different requirements of the measuring medium on the corrosion resistance and the choice of different materials of the diaphragm. Shell with stainless steel material instrument, can be used in the working environment of the more severe cases.
