A Passive ion gauge sensors use hot cathode ionization technology, there is a two models. A IG40 BA is a wide measuring range from 10-2 to 2x10-11 mbar (1.5x10-11Torr) and is protection shield welded in plance, a IG40 EX is a wide measuring range from 10-4 to 2 x 10-12 mbar (1.5x10-12 Torr) and significant reduction of X-ray and
ion desorption effects.
Features and benefits
• Exchangeable cathode in both the Bayard-Alpert and Extractor Gauges
• High accuracy of the measurements due to individually calibrated sensing system
