Selection of Relative Humidity in Constant Temperature and Humidity Test Chamber

Selection of Relative Humidity in Constant Temperature and Humidity Test Chamber

Relative humidity refers to the ratio of the amount of water vapor in the air to the amount of saturated water vapor at a certain temperature and a certain space. The national standard stipulates that it is expressed in %, but people used to express it as: %RH.

The experimentally determined relative humidity under various conditions is:

Human activities 45%-65%

The most favorable disease prevention and treatment environment 40%-55%

40%-60% of libraries, art galleries and museums

Computer room, communication room 45%-60%

Clothing, cotton wool textiles stored 40%-60%

Dairy storage 50%-60%

Candy, snacks storage 40%-60%

With the above comprehensive parameters of humidity under various environments and conditions, we can formulate the corresponding constant temperature and humidity test box test data, such as: paper, electronics, plastic, cotton and linen, food humidity range requirements, In order to standardize product quality, improve new materials in time to improve technology and improve new processes.
