Constant temperature and humidity test chamber, also known as high and low temperature alternating, is suitable for the adaptability of electronics, electrical appliances, automobiles, communications, LCD screens and other products, parts and materials when stored, transported, and used in high and low temperature, hot and humid environments. The test is a reliability test equipment for various types of electronics, electrician, electrical appliances, plastics and other raw materials and devices for cold resistance, heat resistance, moisture resistance, dryness resistance and quality control engineering. It is particularly suitable for optical fibers, LEDs, crystals, inductors, PCBs. , Batteries, computers, mobile phones and other products of high temperature, low temperature, humidity and heat cycle test. It is necessary to choose a suitable constant temperature and humidity test chamber. He will make the following work more effective. Firstly, the volume of the constant temperature and humidity chamber is selected. The volume of the constant temperature and humidity chamber is (W*H*D). When the purchaser can place the tested product (components, components, components or the whole machine) into the climate environment box for testing, in order to ensure that the ambient atmosphere of the tested product can meet the environmental conditions specified in the test specification, the working space of the climate chamber is The following points shall be observed between the outer dimensions of the tested product: Portable And Separable Marking Machine Portable And Separable Marking Machine,Portable Marking Machine,Separable Marking Machine,Separate Fiber Laser Marking Machine Jinan Bodor CNC Machine Co., Ltd. , https://www.lasercuttings.nl
1. The volume of the tested product (W × D × H) must not exceed the effective working space of the test chamber (20-35). For products that produce fever in the test, no more than 30 is recommended;
2. The ratio of the cross-sectional area of ​​the product under test to the total area of ​​the working chamber of the test box on the section is not to be greater than (35-50) (35 is recommended);
3. The distance between the outer surface of the tested product surface and the test box wall should be at least 100-150mm (150mm recommended).
