摘要: A dew point hygrometer wherein separate reflective surfaces reflect light from separate light sources to a single light sensor. One surface is cooled to develop a coating of condensation. The other surface provides a standard to detect contamination build-up on both surfaces, and to detect variations in the operation of the single light sensor.
