  • SF6 gas detector, Sulfur hexafluoride - GazDetect | Gas

    As sulfur hexafluoride can absolutely not be detected without proper equipment (odorless and colorless gas), only an SF6 detector can accurately measure concentrations of this asphyxiating gas and properly monitor SF6 gas hazards. Thus it is advised to use a fixed or portable sulfur hexafluoride detection device or complete system.
