Climatic chambers are equipped with a humidification system that introduces moisture into the testing environment. This system typically consists of a water reservoir or supply, atomizers, or steam generators. By controlling the amount of water vapor released into the chamber, the humidity level can be increased.


Dehumidification System:

Similarly, climatic chambers have a dehumidification system to reduce humidity levels when needed. This system removes excess moisture from the chamber's air. Common dehumidification methods include condensation, absorption, or adsorption. They help regulate the humidity by extracting moisture and maintaining a desired level.


Humidity Control:

Climatic chambers employ precise humidity control systems to monitor and regulate the humidity inside the chamber. Humidity sensors continuously measure the moisture content, and the control system adjusts the humidification or dehumidification mechanisms accordingly to reach and maintain the setpoint.


Humidity Distribution:

To ensure uniform humidity distribution within the chamber, airflow systems or fans are often integrated. These systems circulate the air and distribute moisture evenly throughout the testing space, preventing localized variations in humidity levels.


Humidity Stability:

Just like temperature stability, maintaining humidity stability is critical in climatic chambers. The control system monitors the humidity continuously and makes necessary adjustments to the humidification or dehumidification systems to maintain the desired humidity range. This stability ensures consistent and accurate testing conditions.


Humidity Sources:

Depending on the specific requirements, climatic chambers can introduce additional humidity sources, such as salt solutions, wetted materials, or humidity generators. These sources provide specific humidity levels for specialized testing applications.
