Abstract:
1. Device for determining the dew point temperature and relative humidity, wherein the device comprises a housing and wherein at least two thermocouples are provided inside said housing wherein at least a part of the interior of said housing constitutes a measuring chamber, and wherein one of the at least two thermocouples is shielded from exposure to the measuring chamber; wherein means are provided for changing the temperature of the thermocouples and registering the temperatures and/or the temperature difference between the at least two thermocouples; wherein the thermocouples are arranged in a member exhibiting low thermal conductivity, for example a plastic member, so that only the tip of the thermocouples are exposed to the measuring chamber, of which one thermocouple is shielded; and wherein on the side of the member exhibiting low thermal conductivity not being exposed to the measuring chamber the thermocouples are encased in a heat conductive material and the means for changing the temperature comprising a heating and/or cooling element is arranged in connection with the encasing.
