Select Humidity Range of Climate Chamber

The humidity index given by the temperature and humidity environment test chamber is mostly 20%~98% or 30%~98%. If the temperature and humidity environment test chamber does not have a dehumidification system, then the test chamber with a humidity range of 60%~98% can only perform high humidity tests.

To achieve high temperature and high humidity, just spray water vapor or atomized water droplets into the chamber air for humidification. Low temperature and low humidity are relatively difficult to control.

Since the absolute moisture content is very low at this time, sometimes much lower than the absolute moisture content in the atmosphere, it is necessary to dehumidify the indoor flowing air to make the air dry.

Relative humidity is directly related to temperature. The higher the temperature, the lower the relative humidity. Of course, this is under the same absolute water content.

For example, an absolute moisture content of 5g/Kg (refers to 5g water vapor in 1kg of dry air). When the temperature is 29℃, the relative humidity is 20%, when the temperature is 6℃, the relative humidity is 90%, when the temperature is below 4℃, the relative humidity is above 100%, and condensation will occur in the inner cavity.
