The distance between the racks should be adjusted according to the size, shape, quality and quantity of the products. The air ducts above should not be covered. The product also needs to be at least 5 mm away from the left and right sides of the cabinet. Secondly, the volume of the standard high and low temperature test chamber should be greater than or equal to 3 times the volume of the product. The product should not be placed too dense.
