Kiln Dry / wet and dry temperature to determine Relative Humidity1/8
Our computering system for the kiln dryer uses 4 sets of needles to check wood planks MC and dry + wet temperature in the room to determine the Relative Humidity (using psychrometric diagram)
You wrote "dry temperature is 60 degrees Celcius (140 degrees Fahrenheit), the minimum wet temperature obtained is 45C (113F). Is it normal?"
(Is the wet-bulb located about 5 cm above the water supply and does the wick supply water so that the wick is soaking wet? If there is enough air flow, the warm water in the wet-bulb box will not be an issue, as this heat will be lost as the water soaks up the wick.)

Thank you Gene for your advices.
I presume there is not enough air blowing on the wet-bulb. Could you please advice where is the best spot to put wet tank ? just after the fan ?
