7E Cold Cathode
The 7E cold cathode gauge (also called a vacuum pressure gauge or cold cathode ionization gauge) has a measuring range of 10-8 Torr up to 10-2 Torr. This vacuum meter performs indirect absolute pressure measurements by ionizing gas in the presence of a magnetic field. Unlike hot wire vacuum gauges, the 7E cold cathode gauge is cleanable, resistant to contamination, and less likely to be damaged by incoming gas.

Description
The design of this vacuum gauge allows for easy disassembly, enabling quick cleaning and extended use. The 7E cold cathode ionization gauge can be operated by using the Televac MX200 vacuum controller. Any vacuum controller will automatically operate the cold cathode to provide a full-range vacuum measurement solution when the 7E is used in conjunction with rough vacuum sensors like the 2A thermocouple vacuum gauge or 4A convection vacuum gauge.
