Chilled Mirror Dew Point HygrometersDew Star
Accurate and reliable dew point measurement over an extended range for long periods with our new ACCU-STAR mirror maintenance feature. The Dew Star series of the multifunction and high accuracy provides wide applications which are for the calibration standard of humidity, for the humidity management in a clean room and a dry room, for the dew point measurement of the corrosion gas and etc. Line up of 3 models to cover wide range of application.
What is the chilled mirror method？
Optical condensation hygrometry is a precise technique for determining the water vapor content is gases by directly measuring dew point or frost temperatures.
Using this technique a metal mirror is cooled until it reaches a temperature at which a thin layer of condensation begins to form on it.
The dew layer is detected optically, and the mirror is held at that temperature.
The mirror temperature, measures with a PRT, is an accurate indicator of the dew or frost point.
Because these hygrometers are so accurate, they are used as a standard in many of the world’s metrology laboratories.
