The invention relates to a field of measuring engineering. For increase in speed, sensitivity and accuracy of measurement of a hydrocarbon dew point, a method for hydrocarbon dew point temperature measurement is provided, comprising feeding gas to be studied onto a cooled element with a condensation surface onto which a light flux is directed at an angle providing its reflection in the observation aperture, a cooling of condensation surface of a cooled element and registering the value of the light flux reflected from the condensation surface, advent of the hydrocarbon dew point being determined on the basis of the registered value, and as a material for condensation surface of a cooled element use silicon. The device for hydrocarbon dew point temperature measurement contains a cooled element (4) with condensation surface contained in a housing (1), having openings (2) and (3) for an input and an exit of the gas to be studied, a cooler (5), the temperature sensor (6), the light source (7), located in such a manner that a light flux from it is directed after reflection from condensation surface of a cooled element (4) to the observation aperture (8) on the registrar (9) of the reflected beams, and the cooled element (4) with condensation surface is made from dielectric with refraction factor greater than refraction factor of liquid hydrocarbons.
