Scope of application
PP diaphragm pressure gauges are specifically used in printed circuit board PCB/LCD liquid filtration pumps and petrochemical industries. In the PCB circuit board industry, such as metal etching machine and PCB / LCD cleaning liquid filtration pump, corrosion resistance, can measure high viscosity liquids, gases, widely used in chemical industry various chemical machinery. Such as developing machine, washing machine, etching machine, liquid filter and other equipment. Due to the integrally formed structure, the pressure gauge is less prone to cracks and oil leakage, and has excellent corrosion resistance.
