What technical indicators need to be met by the Shanghai simple household constant temperature and humidity chamber?

The constant temperature and humidity test chamber is a reliability test equipment for cold resistance, heat resistance test and quality control engineering of various electronic, electrical, electrical, plastic and other raw materials and devices, especially suitable for light soldering, LCD, crystal, inductor, PCB, battery. , high temperature and low temperature cycle test of products such as computers and mobile phones.

In the constant temperature and humidity test chamber, when the large sample test is carried out, the rising air flow and the falling air flow will have temperature and humidity deviation. Therefore, the sample position should be carefully placed. When placing the sample, it should be placed in the center of the equipment working space as much as possible. It is not allowed to contact and overlap each other. A certain interval should be reserved for air circulation. It should also be ensured that the sample is easy to move during the test and it is easy to replace the sample.

The constant temperature and humidity chamber has an air outlet and a return air outlet. According to the standard, the volume of the cabinet is greater than or equal to 3 times the volume of the product to be tested. However, in order to save resources, the general recommendation is: the upper part of the inner cavity is 100 mm, and the lower part is 100 mm. 5mm should not be placed on the left and right sides, and the products placed in the box should not be too dense. First, the test items should be placed in the middle of the box. The air duct above and the return air outlet should not be covered. The distance between the left and right sides of the box is at least 5mm. In addition, if the size, shape, weight and quantity of the items to be tested are different, the distance of the rack can be adjusted.
