7F Cold Cathode

The 7F cold cathode gauge (also called a vacuum pressure gauge or cold cathode ionization gauge) has an extremely wide measuring range of 10-11 Torr up to 10-2 Torr (making it an ultra-high vacuum or UHV solution). This vacuum meter performs indirect absolute pressure measurements by ionizing gas in the presence of a magnetic field. Unlike hot wire vacuum gauges, the 7F cold cathode gauge is contamination resistant and is not easily damaged by gas intrusion.

Description

The design of this vacuum gauge allows for bakeout without disassembly. The 7F cold cathode ionization gauge can be operated by the Televac MX200 vacuum controller. Any vacuum controller will automatically operate the cold cathode to provide a full-range vacuum measurement solution when the 7F is used in conjunction with rough vacuum sensors like the 2A thermocouple vacuum gauge or 4A convection vacuum gauge.®
