    Hi Jim,

    I have collected temperature and humidity data for almost 2 years now comparing the inside of my container with a 360 Products venting system against the outside temperature and humidity. I have attached the data file for you to see.

    The most important column is the difference between the temperature inside the container and the dew point outside. A positive number means the inside temperature was above the outside dew point, and condensation should not have occurred. A negative number means the inside temperature was below the outside dew point, so condensation might have occurred if the humid outside air entered the container.

    We are located in Ellisville, Illinois, population 96. Our organization is a 501(c)(3) nonprofit preserving historic buildings. We use the container to store materials and equipment.

    Jim,

    I thought of another way to summarize the data. During the test period there were times when the outside dew point was above the inside temperature. Those were the times when condensation would have been possible if outside air entered and contacted cooler surfaces.

    I hope this information is useful.
