Smart RSS-SF6 Sensor

The RSS SF6 sensor can easily be integrated into OEM systems, where long term stability, repeatability and reliable performance are required. Furthermore, its high-precision NDIR technology also qualifies the RSS SF6 gas sensor for utilisation in numerous laboratory measurements where precision and reliability are of uttermost importance for subsequent processing. Special build-in solutions to provide IP54 protection and easy field gas-calibration are available.
