Consequently, even though two locations used for measuring may be close to each other, both results may be quite different; 3. Dew point : The dew point is calculated by taking into account the humidity and the ambient temperature.

It gives the temperature at which the water vapour contained in the air has reached saturation point forming of cloud, fog, dew, condensation on objects, etc. Measuring Temperature Ambient temperature: Measurement units: In order to choose between units, press the temperature button for approximately 4 seconds.

Display: resolution to 0. In the event of a sudden change in the temperature, it is necessary to allow the sensor enough time to reach the ambient temperature. This duration will depend on the temperature difference and wind force.
