  • SF6 Gas Measurement Theory - MBW Calibration AG

    MBW has more than forty years of experience measuring water vapor (moisture, humidity, dew point, frost point, ppm v, ppm w) in SF 6 gas applications. We have supplied thousands of dew point measurement systems, many of which remain in daily use despite being in use for 20…30 years. Our fundamental measurement technology provides the highest possible accuracy and long-term stability so that engineers can depend on good measurements when they need them, without regular and expensive sensor
