What Are the Technical Differences Between Constant Temperature and Humidity Chamber and Constant Temperature Chamber?

In daily work, customers often say that they want to purchase a constant temperature box. But after consulting, it is found that what the customer actually needs is a constant temperature and humidity chamber that covers humidity and low-temperature functions. Then what are the differences between the constant temperature and humidity chamber and the constant temperature box? 

1. The functions of the constant temperature and humidity chamber and the constant temperature box are different

Both thermostats and constant temperature and humidity chamber belong to the temperature and humidity series of environmental testing equipment. Although the two devices are not very different in appearance, they are actually quite different in function.

Because the constant temperature test chamber has more perfect performance than the constant temperature and humidity drying oven, it can also be said that it is developed on the basis of the constant temperature and humidity drying oven.

The constant temperature chamber is a test box that ranges from a room temperature of 25 degrees Celsius to a high temperature of 400 degrees Celsius. It has the functions of high-temperature aging test and high-temperature baking. During the temperature rise, the temperature is kept constant to detect and test the high-temperature resistance of the test product, or to achieve the purpose of drying products by heating. It is currently widely used in major industrial industries, especially in the electronic component industry.

The constant temperature and humidity chamber is a damp-heat aging test box, which has the functions of high temperature, low temperature and humidity. The main function of this equipment is the function of damp and heat aging test. It also has separate high temperature test, low temperature test and other functions. The constant temperature and humidity chamber is an extremely powerful test chamber equipment, which is widely used in major industries, research institutes and universities.

2. Humidity test of the constant temperature and humidity chamber

When the constant temperature and humidity chamber do the humidity test, the wet ball gauze used must be special, the fabric of this gauze must be woven from linen, and the wet ball gauze must be replaced every 3-6 months of use, otherwise it may affect the accuracy of the test. The gauze must be placed in the reservoir when changing.

If the high temperature does not require humidity for a long time, the wet ball gauze can be removed, otherwise the wet ball gauze will become very hard under the condition of continuous high temperature, which will cause it to not absorb water.
