Chilled Mirror Dew Point Meter

Line up of 3 models to cover wide range of application.

Chilled mirror dew point meter.

Drift free a chilled mirror sensor will measure consistently every time. The model 200m is a complete instrument for the measurement of atmospheric dewpoint ambient temperature relative humidity or other psychrometric variables. These self contained dew point hygrometers combine the inherent accuracy reliability and long term stability of optical chilled mirror technology with the convenience and ease of use of demanded by industry. In terms of dew point the equivalent accuracy is 0 175 c.

The fundamental nature of this method means that chilled mirror instruments can be used as either extremely reliable and stable field instruments or as laboratory reference standards for the calibration of other devices. Features highly precise chilled mirror dew point technology. Michell s chilled mirror dew point meters are precision instruments for critical measurement and control applications. 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.

Accurate and reliable dew point measurement over an extended range for long periods with our new accu star mirror maintenance feature. The sensor head is optimised for fast response to low moisture levels and features the rrs system for high sensitivity and a dew point accuracy of 0 1 c. The cmh series is a range of chilled mirror dew point hygrometers designed to give a primary measurement of water vapour content of gases. It employs the very reliable optical chilled mirror sensing technique which provides a primary measurement of dewpoint and is traceable to nist.

Calibration the s8000 s4000 and optidew can be used to calibrate relative humidity and dew point instruments. The 473 shx dew point mirror is designed for dew point measurements in high temperature applications. The optica hygrometer may be used with five fully interchangeable chilled mirror sensors to provide a measurement range from 112 f to 185 f 80 c to 85 c dew point with 0 36 f 0 2 c or better accuracy. In both cases this is close to the accuracy available from a good laboratory chilled mirror instrument.

Accuracy chilled mirror technology is accurate to 0 1 c 0 18 f s8000 and s4000 model. Aw meters that use a chilled mirror typically claim an accuracy of 0 003 aw a figure which is argueable at best.
