BASIC INFO
MICHELL S8000 RS High Precision SF6 GAS Chilled Mirror Hygrometer
The S8000 RS chilled mirror sensor directly measures the formation of condensation, giving long-term and unmatched, drift-free readings of dew-point and relative humidity. It offers a wide measurement range from -90 to +20°C dew point. Fully automated control of the auxiliary cooling system means that no operator intervention is required even if the measured dew point changes from one end of the range to the other.
