This PP diaphragm pressure gauge, also known as full plastic diaphragm gauge, is a corrosion-resistant pressure measuring instrument designed for harsh chemical environments. It is mainly used for measuring pressure of corrosive, high-viscosity, or particle-containing media such as acids, alkalis, salts, and other chemical solutions. Its key feature is the use of polypropylene (PP) diaphragm and housing, providing strong corrosion resistance and protecting the internal sensing element from damage in aggressive media.

• Chemical and electroplating industry: used for measuring pressure of electroplating solutions, acid and alkali tanks, and chemical reactors containing strong corrosive media such as hydrochloric acid, sulfuric acid, and sodium hydroxide solutions.
• Water treatment and environmental protection: used in wastewater and sewage treatment systems, as well as pressure monitoring of corrosive chemical agents such as flocculants and disinfectants.
• Electronics and semiconductor industry: used in wafer cleaning, etching processes, and pressure measurement of corrosive chemical process fluids.
• Pharmaceutical and food industry: used for pressure monitoring of chemical solutions with corrosive additives, including acidic beverages and pickling solutions in food processing.
• Laboratory and research applications: suitable for measuring pressure of various corrosive media in chemical experiments and research environments.
