Televac's new All Metal Enclosed B/A-S Ionization Gauge with Spring Supported Filament is designed and engineered to provide highly accurate vacuum measurement with less calibration errors. The gauge offers a combination of features that are superior to conventional B/A (Bayard-Alpert) gauge designs including a spring supported filament for greater stability.

· Universal Design–allows gauge to be easily used with other manufacturers B/A controllers

· Spring Supported Filament–delivers a more uniform output over variations in temperature and age with less calibration errors

· Grounded Metal Enclosure Wall and Conducting Shields–provide constant potential and protect the delicate filament and anode assemblies from unintended shock and physical damage

· Thoria Coated Iridium Filament–minimizes burnout for longer filament life

· Available Televac MM 200 Hot Filament Controller and Cable–provides a single source solution (or system) for critical vacuum measurement
