DEW POINT HYGROMETER

A circular polished and chrome plated mirror is enclosed on one face by a cylindrical tube with a clear window. Air is drawn into the enclosure by a small air pump either from the surrounding ambient or from another source. The mirror is cooled electronically and its temperature is recorded by a close tolerance thermometer located at its geometric centre.

The temperature at which mist is seen on the mirror is the dew point, which is then recorded. Learn about DEW POINT HYGROMETER specifications for optimal educational outcomes.. A second identical thermometer for recording the dry bulb temperature is also supplied. These two values allow either direct calculation of the air condition or determination from the charts supplied. Learn about DEW POINT HYGROMETER price for optimal educational outcomes.. As the mirror is electrically cooled, unlike more traditional evaporative instruments, the process is quickly reversible allowing repeated measurements.
