  • Mountable in any orientation
  • Interchangeable with 7E, 7FC, 7FCS
  • Excellent customer support

The Televac® 7F cold cathode gauge (also called a vacuum pressure gauge or cold cathode ionization gauge) has an extremely wide measurement range from 10-11 Torr up to 10-2 Torr (making it an ultra-high-vacuum or UHV solution). This vacuum gauge makes indirect absolute pressure measurements by ionizing gas in the presence of a magnetic field. Unlike hot filament vacuum gauges, the 7F cold cathode gauge is contamination resistant, and isn’t as easily damaged by inrushes of gas.

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, MX200 EthernetIP, or the MX200 PROFINET. All of these vacuum controllers 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.
