ABSTRACT:
The invention relates to measuring engineering. In order to increase accuracy by increasing sensitivity, for the inventive dew point measurement method a light flux polarized in the plane of incidence thereof is used and directed towards the condensation surface of a dielectric cooled element at an angle at which the light flux is not reflected from the condensation surface of the cooled element in the absence of condensate.
