The three comprehensive test chambers can simulate various complex environments and provide important assistance for the detection of various test objects. What necessary standards should we refer to when selecting the three comprehensive test boxes for this high-tech product that we rely heavily on? Let's discuss this issue with everyone.

1、 Selection of Volume for Three Comprehensive Test Chambers

This is an important indicator that must be considered for different test samples. Normally, the ratio of the windward area of the test sample to the total area of the three comprehensive test chamber studios should be within (35-50)%. In addition, the distance between the outer surface of the test sample and the wall of the test box should not be less than 100-150mm. For test samples, the volume should be less than (20-35)% of the effective working space of the test chamber, and for products that generate heat during the test, it is recommended to choose no more than one tenth.

2、 Selection of temperature range for three comprehensive test chambers

Normally, the temperature range of the three comprehensive test chambers can basically meet the needs of the test, but there are also some special cases. Unless there are special circumstances, the upper temperature limit cannot be arbitrarily raised. Because the higher the upper limit temperature, the greater the temperature difference between the inside and outside of the three comprehensive test boxes, and the uniformity of flow inside the boxes will be affected. The usable volume of the studio will also be reduced. Moreover, the higher the upper limit temperature, the higher the heat resistance requirements for the insulation material in the interlayer of the box wall. The requirements for sealing of the box will also increase, and the production cost of the product will also increase.

3、 Selection of Cooling Methods for Three Comprehensive Test Boxes

If the three comprehensive test chamber is equipped with a refrigeration system, the refrigeration system needs to be cooled. This is to ensure the smooth progress of the experiment and facilitate obtaining more accurate experimental data.

So, if you want to purchase the three comprehensive test box product, you can refer to the above aspects. In addition, the editor also suggests that you should learn more about relevant knowledge in advance, which is conducive to choosing a more ideal three comprehensive test box.
