VACGEN Ion gauge heads - Spares and accessories available

Thoriated iridium filaments are iridium wire coated with a thin thoria coating. These filaments have a lower work function than standard tungsten filaments, and are capable at operating at a lower temperature than tungsten filament gauges with less CO and CO2 produced.
