From which surface temperature there is a risk of condensation formation depends on the current air temperature and humidity. Even in tents and pavilions, where warm air rises to the cold tent roof, condensation often forms on cool evenings. This effect can be often seen on mirrors after a long hot shower and on glasses when someone enters a warm humid room after being in a cold environment outside. Since the warm air can absorb more water vapor than the cold one, condensation occurs on cold surfaces when warm air cools down. To prevent any damage to the moisture-sensitive materials, the formation of condensation on these materials must be avoided. A water vapor quantity of 8 g / m³ as absolute humidity corresponds to:Īt 10 degrees Celsius 8 g / m³: 9.4 g / m³ = 0.8511 = 85.1% relative humidity,Īt 15 degrees Celsius 8 g / m³: 12.8 g / m³ = 0.6250 = 62.5% relative humidity,Īt 20 degrees Celsius 8 g / m³: 17.5 g / m³ = 0.4571 = 45.7% relative humidity,Īt 25 degrees Celsius 8 g / m³: 23.0 g / m³ = 0.3478 = 34.8% relative humidity. ![]() The relative humidity is often abbreviated as rH or RH. ![]() It specifies the ratio of the available water vapor content to the maximum possible water vapor content (saturation amount) under the current temperature and pressure conditions in percent. Therefore, the relative air humidity always depends on the current temperature. The maximum amount of water vapor that can be absorbed from one cubic meter of air increases with the temperature. ![]() The absolute air humidity is usually given in g / m³, so it shows how many grams of water vapor are contained in one cubic meter of air. Humidity meters show the humidity as an absolute or relative value.
