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.

The industry’s best value for a rugged digital vacuum controller & gauge for measuring through 6 decades of wide range rough vacuum with precise accuracy.
