Diaphragm seal pressure gauge with glycerin filled

Brief Description

To make general pressure gauge applicable to medium which are strong corrosive, high-temperature, high-viscosity, easy to crystallize & solidify, and with suspended solid, also to avoid direct contact between general pressure gauge and medium, to make gauge easy to wash, we combine diaphragm isolator with general pressure gauge, which is a diaphragm-seal pressure gauge. Diaphragm-seal pressure gauge is mainly used in petrochemical industry, alkali-making, chemical fiber, dyeing, pharmacy, food and butyr-making industries to measure medium pressure.
