Chilled mirror dew point hygrometers dew star.
Chilled mirror dew point meter.
Drift free a chilled mirror sensor will measure consistently every time.
Calibration the s8000 s4000 and optidew can be used to calibrate relative humidity and dew point instruments.
Our flagship chilled mirror hygrometer capable of measuring as low as 90 c dew point in a compact lightweight package.
The cmh series is a range of chilled mirror dew point hygrometers designed to give a primary measurement of water vapour content of gases.
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.
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.
Accurate and reliable dew point measurement over an extended range for long periods with our new accu star mirror maintenance feature.
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.
It employs the very reliable optical chilled mirror sensing technique which provides a primary measurement of dewpoint and is traceable to nist.
Accuracy chilled mirror technology is accurate to 0 1 c 0 18 f s8000 and s4000 model.
In terms of dew point the equivalent accuracy is 0 175 c.
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.
Aw meters that use a chilled mirror typically claim an accuracy of 0 003 aw a figure which is argueable at best.
In both cases this is close to the accuracy available from a good laboratory chilled mirror instrument.
Features highly precise chilled mirror dew point technology.
Basic principle of cold mirror dew point meter when a certain volume of gas is cooled uniformly under a constant pressure the partial pressure of the gas and the moisture in the gas remains unchanged until the moisture in the gas reaches a saturated state and the temperature in this state is the dew point of the gas.
The model 200m is a complete instrument for the measurement of atmospheric dewpoint ambient temperature relative humidity or other psychrometric variables.
