The constant temperature and humidity chamber and the high and low temperature test chamber both test the adaptability and reliability of the items in different climatic environments. There is no big difference in appearance between the two, but the performance and use are different. After understanding their differences, users can choose the appropriate device according to their product testing needs.
First, compare the components and functions of the two devices.
The components of the high and low temperature test box mainly include refrigeration, heating, control, air circulation, sensors and other systems. The functions include high temperature, low temperature, and temperature cycle tests. In comparison, the constant temperature and humidity test box has an additional humidity system. It can carry out high temperature, low temperature, humidity cycle test.
Whether it is literally or in terms of working principle, it can be seen that the difference between the two devices lies in the word "wet", that is, the high and low temperature test box can only do temperature tests, while the constant temperature and humidity box not only conducts temperature tests, but also A humidity test can be done.
Since the latter has more functions than the former, the latter is about 2,000 yuan more expensive than the former. When the user chooses, if the budget allows, try to choose the latter. Even if the temperature test is only required at present, if the later product needs to be subjected to the humidity test, it will cost more to purchase an additional device.
Talking about the difference in functions, we also talk about a difference between the constant temperature and humidity chamber and the high and low temperature test chamber in terms of application. The former has a wider range of applications, including aerospace, electronic communications, instrumentation, medicine, agricultural scientific research and other industries; it can test the high and low temperature and dry and wet tolerance of items.
The high and low temperature test box is suitable for automobiles and motorcycles, aerospace and navigation, scientific research institutes and other fields, and only tests the performance of items in high and low temperature environments.
As environmental inspection equipment, the two play an important role in the quality inspection and improvement of user products and the promotion of scientific research results.
