Relative Humidity of air (RH)
Often expressed as a percentage, relative humidity is the amount of vapour in the air relative to the amount that it would hold if saturated -100%RH at a given temperature-.
Relative humidity and temperatureThe amount of water vapour the air can hold when saturated increases with its temperature.
If the air is heated up while the real amount of water remains constant, the relative humidity content (%RH) decreases.
Similarly, if air is cooled down, the amount of water vapour that it can hold decreases and the relative humidity content (%RH) increases.
CondensationThe condensate forms when there is a excess of water in saturated air.
Relative humidity measurementRelative humidity and temperature can be measured on site thanks to a portable thermo-hygrometer.
Within the monitoring of indoor air quality, a stand-alone logger allows to monitor CO2 as well as comfort parameters in time.
This shock-resistant thermo hygrometer allows to measure humidity, temperature, dew point, mixing ratio or air absolute humidity.
This CO2, humidity and temperature logger meets the requirements of the French decree n°2012-14 concerning the monitoring of the indoor air quality of public opened buildings. It allows stuffy air
Its CO2 calibration is simple and quick.
