Features and Benefits:

  • Low cost vacuum gauge
  • Easily cleaned vacuum gauge for extended sensor lifetime
  • Durable Penning ionization gauge construction
  • Reliable cold cathode ionization gauge technology
  • Contamination resistant, resistant to inrushes of gas, and cleanable
  • Mountable in any orientation
  • Excellent customer support

The Televac® 7B cold cathode gauge (also called a Penning ionization gauge or cold cathode ionization gauge) has a measurement range from 10-7 Torr up to 10-3 Torr. This vacuum gauge makes indirect absolute pressure measurements by ionizing gas in the presence of a magnetic field. Unlike hot filament vacuum gauges, the 7B is cleanable, contamination resistant, and isn’t as easily damaged by inrushes of gas.

The design of this vacuum gauge allows for easy disassembly, enabling quick cleaning and extended use. The 7B Penning ionization gauge can be operated by the Televac® MX200 vacuum controller or as an active gauge via the MX7B. Any vacuum controller will automatically operate the 7B to provide a full-range vacuum measurement solution (from atmosphere/760 Torr to 10-7 Torr) when the 7B is used in conjunction with rough vacuum sensors like the 2A or 4A. Active vacuum gauges can also be combined using the MX2A/MX4A and MX7B to provide full-range vacuum measurement.
