    RSS-SF6 is a non-dispersive infrared (NDIR) gas sensor that uses dual-wavelength technology for ambient air monitoring.


    Designed for analysis of SF6 leakage quality and purity within gas insulated switchgear (GIS)


    RSS-SF6 sensor has long term stability, repeatability and reliable performance and high-precision and easy to calibrate Modbus ASCII or RTU data communication offer a variety of options to connect the RSS-SF6 sensor to a controller.
