Chilled mirror hygrometer exceptional response to trace moisture!

The S8000 hygrometer’s accuracy at very low temperatures (below -80°C dp) is due to a new measurement system which Michell Instruments calls ‘RRS’. RRS is a sophisticated technique that detects very small changes in moisture condensed on the chilled mirror surface. This guarantees both high sensitivity and fast response when measuring low dew points. The S8000 is also the smallest and among the lightest chilled mirror instruments on the market with the ability to quickly measure dry dew points while offering an accuracy of ±0.1°C. The S8000 stands out from other instruments in its class in its ability to measure low dew-points without requiring external cooling. Its compact size means that it is convenient for use either as a bench-top instrument or installed in a 19” rack system. The touch-screen interface is highly intuitive and makes the instrument simple to use. The ability to precisely measure trace moisture makes the S8000 an ideal reference instrument for moisture calibrations and it is popular in calibration laboratories. Its fast response and high accuracy give it an advantage in verifying the purity of industrial gases and for ensuring the quality of semiconductor gas supply. The S8000 is available with UKAS (ISO17025) accredited calibration, traceable to NIST. • Michell products are marketed in Ireland by Instrument Technology.
