popup.description2
A prototype of an automated condensing hygrometer, built on the basis of a cooled mirror and an optoelectronic system for determining the dew point of gases in the aqueous phase, was developed and manufactured.
The created hygrometer uses a new method of measuring the dew point, which consists in measuring several dew points at different cooling rates of the mirror and constructing on these points the experimental characteristic of the fixed dew point of the device on the cooling rate of the mirror, which experiments show is linear. Approximation of this dependence to the theoretically zero cooling rate of the mirror gives the true value of the dew point, which allows to solve the fundamental problem of influencing the accuracy of measuring the dew point of the cooling rate of the mirror and significantly increase the accuracy of its determination.
The accuracy of determining the dew point by the new method is ± 0.2 ° C.
