Today we rurned off the KOACH filter for 30-60 minutes then the optical table was condensated. The picture of condensation is attached.
We should consider about the temperature in PSL room. the cooler preset temperature would be too low.
Temperature and humidity data on this day. The vertial black line is around when the cooler was turend on again. At that time both humidity and temperature rose up, which is strange if the cooler turned on...?
