I own a commercial chest type refrigerator with a glass door on top. Occasionally condensation forms on the glass. I borrowed a hand held dew point meter and found: Room Temp=89.5F; Dew Point=76.8F. The glass surface measures 80.8F and has condensation?!?!? This is not detrimental, but how can this happen? The tools for measuring temp/humidity/dew point are calibrated units. Is there a phenomenea that can cause this? NOTE: The door frame is non-pourous (steel) and there is minimal air movement over the door. Condensation only occurs on the left center of the glass (right side glass surface temp is much higher, around 84F). The glass is approx 14" x 37" in size.
Re: Is there a phenomenea that can force condensation at temps above dew point?
