The anti-corrosion diaphragm pressure gauge is a new variety developed and designed based on the advanced technology of ordinary diaphragm pressure gauges introduced from Japan and according to user needs. The main component diaphragm connector is made of PVS polyvinyl chloride material, the diaphragm is made of PTFE polytetrafluoroethylene, and the instrument housing is made of NJ phenolic film plastic, which has good anti-corrosion performance and is suitable for measuring the pressure of gases or liquids with strong corrosive effects such as chlorine gas, hydrochloric acid, nitric acid, etc.
