◆This product is suitable for the safety performance test of electronic components, providing reliability test, product screening test, etc. At the same time, through this equipment test, the reliability of the product can be improved and the quality control of the product can be carried out.
◆All functions are controlled by computer, which is a self-developed software with a good operation interface, which makes the user's operation and monitoring easier and more intuitive. The hold function can keep the program you are running at the current state and can be temporarily changed The value of this program segment can be set on the screen as the time parameter, so that the switching of cooling, heating, and blue transfer will be automatically carried out according to the set value.
◆The cold box and hot box are independently controlled, and the doors are independent of each other, which expands the scope of use of the test box (one box for three purposes), and the product's heat preservation effect can be fully guaranteed.
◆The door of the Test Chamber is interlocked with the circulating fan and the blue drive to protect the safety of the operator. Once the door is opened, the power supply of the circulating fan and the blue drive will be cut off automatically.
◆There are standard lead hole tubes on the top of the box, which is convenient for users to introduce sensor lines, detection cables and other types of leads into the box.
◆The switching time between low temperature zone and high temperature zone is ≤15 seconds, and the temperature recovery time is ≤5 minutes.
