Collection: Sapphire Capacitance Diaphragm Gauges

We offer high-efficiency, high-quality, easy-to-use Sapphire Capacitance Diaphragm Gauges developed with the latest technologies. The front-end film deposition and etching processing use various gases that may cause film deposits on the sensor diaphragm of the vacuum gauge used in these processes, resulting in a shift of its zero point. These shifts can require film deposition and etching equipment operators to adjust the vacuum gauge more frequently, slowing down the manufacturing process. Azbil’s Sapphire capacitance Diaphragm gauges were designed to reduce Zero Point Shift.
