Opening and closing the door

Test procedure:

 Due to the constant gassing with nitrogen the relative humidityGlossaryrelative humidityPercentage ratio between water vapor pressure and saturated water vapor pressure over a clear and even water surface. On this basis it is easy to evaluate how quickly evaporation will proceed or how large is the danger of condensation. The quantity of water vapor which would be needed for saturation increases with increasing temperature. Similarly the relative humidity of a given air mass falls with increasing temperature. Temperature is therefore an important factor in assessing relative humidity and condensation. inside a desiccator is 15 %. A SICCO Gas Dosing Controller is connected during the lead in of nitrogen in order to control the gas supply and monitor the relative humidityGlossaryrelative humidityPercentage ratio between water vapor pressure and saturated water vapor pressure over a clear and even water surface. On this basis it is easy to evaluate how quickly evaporation will proceed or how large is the danger of condensation. The quantity of water vapor which would be needed for saturation increases with increasing temperature. Similarly the relative humidity of a given air mass falls with increasing temperature. Temperature is therefore an important factor in assessing relative humidity and condensation.. The attainable required humidity is adjusted to 10 %, the flow rate to 8 Liters / minute and the pressure reducer on the nitrogen bottle to 0,5 bar. The door of the desiccator is opened completely for 30 seconds. The curves show the relative humidityGlossaryrelative humidityPercentage ratio between water vapor pressure and saturated water vapor pressure over a clear and even water surface. On this basis it is easy to evaluate how quickly evaporation will proceed or how large is the danger of condensation. The quantity of water vapor which would be needed for saturation increases with increasing temperature. Similarly the relative humidity of a given air mass falls with increasing temperature. Temperature is therefore an important factor in assessing relative humidity and condensation. versus time.

Results:

The opened door causes an air exchange and thus the relative humidityGlossaryrelative humidityPercentage ratio between water vapor pressure and saturated water vapor pressure over a clear and even water surface. On this basis it is easy to evaluate how quickly evaporation will proceed or how large is the danger of condensation. The quantity of water vapor which would be needed for saturation increases with increasing temperature. Similarly the relative humidity of a given air mass falls with increasing temperature. Temperature is therefore an important factor in assessing relative humidity and condensation. inside rapidly increases. By closing the door the gas dosing controller starts working again and the work space is purged again with nitrogen. After approx. 30 minutes the initial value is reached again.
