| 1212561 | 2011-06-29 09:30:00 | Right now I have inside 18.4degC 53%, outside 4.8degC 81% measured using D.S.E. Deluxe Weather Station with outside remote unit, if I bring the remote unit inside it quickly corresponds to the main unit readings. According to the psychometric chart, at 4.8degC (dry bulb) 81% humidity, there is ~0.004 kg of water per kg of dry air; at 18.4degC (dry bulb) 53% humidity, there is ~0.007 kg of water per kg of dry air. This means that the air inside has actually got more moisture in it than the air outside. |
