Gauges & Controllers
Every Thermionics thermocouple vacuum gauge tube is individually calibrated and is matched to perform as every other tube of the same model so tubes can be replaced without the need to recalibrate the gauge controller.
Bayard-Alpert design, easily outgassed grid, Nonex, Pyrex, or Kovar tubulation. Thoria-coated iridium filament (burnout resistant) or dual tungsten filaments. Range: 10-3 to 10-10 Torr
Cold cathode discharge gauges are an economical and durable alternative to hot filament ionization gauges in the high vacuum pressure regime.
