7B Cold Cathode
The Televac® 7B Cold Cathode Meter (also called Penning Ionization Meter or Cold Cathode Ionization Meter) has a measuring range of 10-7 Torr up to 10-3 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 7B is cleanable, resistant to contaminants, 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 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.
