P740 series_High temperature service pressure gauge
Service intended
P740 series have diaphragm seal to be combined with a pressure gauge, and measure the melted plastics, fiber, and synthetic under high pressure. It is suitable to be used for the situation where corrosive, contaminated, hot and viscous pressure mediums are present during the chemical or food process.
