Absolute humidity, mixing ratio
Absolute humidity?Absolute humidity is the water vapour content in the air (in gramme per cubic meter of air).
The mixing ratio of a volume of air is the rapport of the mass of water vapour content on the dry mass of air. It is expressed in g/kg.
Absolute humidity measurementMeasuring absolute humidity and mixing ratio can be done using a thermo-hygrometer.
Fitted with a humidity probe, this shock-resistant thermo hygrometer allows to measure humidity, temperature and dew point, mixing ratio...even in changing environments.
This humidity tester is designed to measure moisture in piles of paper and line paper thanks to its sword sensor 30cm long. This air humidity meter is also ideal to monitor the climate of printing rooms and paper depot and allow to log measurements.
Air quality? Energy efficiency?
Reconciling the two upstream avoids the costs related to amendment works after building or refurbishment: work costs, social costs –health, absenteeism- and environmental impacts.
Exploitation mode and ways of life have a notable share in “global cost”.
