A heat conducting support having electrodes is located in a chiller block. The electrodes form a temperature sensor, a heater electrode and electrodes for the measuring of the conductivity. The electrodes are covered by an electrically insulating layer, which layer limits or defines, respectively, over a length L a bedewable surface. The chiller block is encased in a heat insulation and its temperature is measured by a second temperature sensor. The cross-sectional area of the heat transfer between chiller block and bedewable surface is substantially smaller than the bedewable surface itself. This makes it now possible that the temperature at the bedewable surface during the forming of the condensate is determined substantially by the temperature of the condensate at the bedewable surface such that increasing formation of condensate a plateau is determinable at the dew point temperature.
