Condensing is after heat exchange, under an atmospheric pressure, when the temperature is lower than the dew point temperature, the water vapor in the air will condense on the surface.
Therefore, under this condition there is no absolute correlation with the difference of a few degrees, but it will be related to the relative humidity.
When the relative humidity is higher, the dew point temperature will be higher.

When the relative humidity reaches 100%, and the dew point temperature is equal to the air temperature then it will condense into dew. When the humidity reaches 100%, it will begin fogging, and the air naturally starts to condense water vapor into the fog.

eyc-tech dew point transmitter is suitable for measuring high pressure and low humidity environment.
Applications：Compressed air system, Freezer, Adsorption machine, Plastic dryer, Industrial drying process, Paper, Chemical process monitoring.
