Since 1962 Troy-Onic has been manufacturing electronic glass components, specializing in bayard alpert ionization gauges. We supply both O.E.M.s and Hi-Vac equipment distributors with high quality gauges. In addition to standard glass bodied Bayard Alperts, we also make flange mounted nude gauges with both normal Bayard Alpert components and Ultra High Vacuum (UHV) ionization gauge components. We produce both Tungsten and Thoria or Yttria coated iridium filaments and replacement filament assemblies (RFAs) for both Bayard Alpert and UHV ionization gauges, as well as filament assemblies for specialized applications such as helium leak detectors, etc. Iridium and tungsten filament assemblies are a large part of our business, specializing in both Thorium & Yttrium Electrophoresis coatings In addition, we are still dedicated to the development of new glass technology applications and custom filament assemblies. We welcome the opportunity to work with electronic component designers to apply low cost glass fabrication and resistance spot welding technology to new concepts. Glass fabrication is very flexible allowing rapid modification of design configurations, resulting in low cost development.
