A humidity chamber is used to test the effect of humidity and temperature on products, materials, components, and instrumentation.
Uses of Humidity Chamber:
Humidity-controlled chambers are common in testing laboratories in a variety of industries,
-Its commonly used in pharmaceutical laboratories -Called as a stability chamber in which the effect of temperature and humidity is tested
-On Medicines (Some chambers test the effect of lighting).
- Humidity chamber / environmental chamber common in food laboratories. There they test the effect of humidity and temperature on food products.
-Cosmetics labs, testing the effect on creams.
-Laboratories that grow seeds, plants, and insects use Temp./Humidity chambers.
Types of Humidity chambers:
Standard humidity chambers check temperature and humidity.
There are chambers that simulate daylight.
Humidity chambers with light are required mainly in the field of plant science, insects and little in the field of pharmaceuticals.
How does Humidity Chambers Work?
The device consists of three systems:
-Heating System,
-Cooling system
- Humidity system
There is an effect between temperature and humidity and there is a limitation in the ability of the chamber to produce the Temperature and humidity required.
The humidity chamber has a behavioral graph of humidity and temperature
Which are interdependent (psychometric table).
Temperatures and humidity can be determined in the psychometric table only.
The humidity system is usually an ultrasonic or boiling system that produces steam.
The temperature and humidity in the chamber are kept stable by a controlled temperature and humidity controller. The uniformity of temperature and humidity in the chamber is maintained by an air circulation system. The device is divided by several shelves, and the lighting is composed on them.
Choice of A Humidity Chamber
- Check that the required temperature and humidity are possible in the psychometric table of the chamber.
- The size of the inner compartment, the area of the shelves and the number of shelves should be adjusted to the number of products to be checked, It is important that the chamber be large enough.
-If a huge chamber is needed, it is better to choose a room in the laboratory and assemble in it temperature and humidity control systems.
