Ultra High Vacuum Ion Gauges
Nude Bayard-Alpert ion gauges covering the vacuum range 1 x 10-3 to 3 x 10-11 mBar. They are intended for electron-bombardment degas. Available with a range of filament materials.
Wide UHV measuring range of 1 x 10-3 to 3 x 10-11 mBar
Replaceable twin tungsten, thoria or yttria-coated filaments available
Individual glass compression seals around each feedthrough pin are more economical and robust than ceramic, resulting in a less expensive and more rugged gaugehead
Central collector pin is inherently guarded against leakage currents by the grounded bulk of the flange
