S8000 Chilled Mirror Hygrometer
High-precision hygrometer combines straightforward operation w/ very high sensitivity to changes in moisture content
The S8000 precision hygrometer provides a direct measurement of dew point, temperature and pressure. Suitable for both industrial and laboratory applications, the instrument is compact and self-contained.
Dew-point measurement is based on the proven, fundamental optical chilled mirror measurement principle, giving long-term reliable humidity measurement over the entire operating range. The S8000 uses this measurement to offer a range of available measurement units including ppmV, absolute humidity, relative humidity and ppmW.
