  • Sulfur Hexafluoride Detector - SF6 Monitor - SafetyGas

    Hexafluoride Detector - SF6 gas. A sulfur hexafluoride detector monitors concentrations of this gas in the air and warns in case of danger. SF6 gas - CAS 2551-62-4 - is mainly used as an electrical insulator, in many industries and can also be used in medical applications (especially disinfection). Sulfur hexafluoride is not classified as a toxic gas; however it is a dense gas that replaces oxygen in the air, which can lead to asphyxiation.
