RHS 473 Chilled Mirror

Chilled mirror condensation technology provides highly precise, stable and repeatable results. Water vapor condenses onto a temperature controlled mirror surface and the €˜dew point€™ is detected with advanced optical electronics. Since dew point is specific to water vapor concentration and not temperature dependent, measurement precision is consistent across the full application range including high temperature and humidity conditions in climatic test chambers.

The RH Systems Model 473 Dew Point Mirror is a portable instrument equipped with a separate measuring head for both spot and continuous measurement of Dew/Frost point and temperature in air and gas mixtures. Based on the chilled mirror principle, the 473 ensures direct and accurate humidity measurement.
