Description of Michell S8000 RS

The Michell S8000 RS is a high-precision, low dew-point hygrometer designed to meet the demands of humidity calibration facilities and many high-value manufacturing and industrial applications. Based on the design for our flagship S8000 -100 High-Precision Chilled Mirror Hygrometer, at the heart of the new instrument is a unique advanced optics system to achieve reliable, repeatable measurements of low frost points down to -90 °C, with an accuracy of ±0.1 °C, without the need for additional cooling.

Applications

  • Reference humidity measurements in standards laboratories
  • Reference instrument in humidity calibration facilities
  • Precision moisture measurements in research and development
  • Measurement standard for high-purity gas manufacture
  • Measurement standard for semiconductor dry gas supply
  • Clean/dry room monitoring
  • Metallurgical processes
