Porter® CDG020D
vacuum gauge
The INFICON Porter® CDG020D Capacitance Diaphragm Gauge is designed forstable long time performance in industrial
environments. The ceramic sensor provides excellent span stability over many
years paired with outstanding zero stability. An in-situ sensor architecture guarantees a short and long term temperaturestability.
Our Porter® vacuum gauge comes withfully digital electronics and defines flexibility in integration in a humble, reliable,
always available and never overpaid way.

ADVANTAGES AT A GLANCE
 More gauge for less
 Smallest in class Outstanding stability
 Chemical resistance Digital signal processing

TYPICAL APPLICATIONS Pressure monitoring Vacuum coating, food packaging
 Vacuum coating, sterilization
 Analytical Vacuum ovens, puller
