Product Data Sheet · Laboratory Equipment
SF6 Dew Point Tester NSFD-100 measures SF6 gas moisture content with a dew point range of −80°C to +20°C and micro water measurement up to 19999 µL/L. It provides 0.1°C dew point resolution, rapid response, and intelligent self-calibration for consistent moisture measurement. The automatic dryer helps shorten measurement time, while the dynamic curve displays dew point changes during testing. The dew point tester supports SF6 gas moisture testing, dew point monitoring, gas quality inspection, and condition assessment of SF6-filled electrical equipment.
