Principle of operation

Measured parameter Dew Point
Operating principle

Thermoelectric Chilled Mirror Hygrometer
Operating principle information should be extended to explain servo-control of mirror temperature and detection of condensation deposit.
Note possible ambiguity between dew and frost-point temperatures for low mirror temperatures.
Operating principle is extended to include cryogenic cooling in addition to thermoelectric.
