Advanced PID control technology is used to accurately control the opening degree of the electronic expansion valve, providing appropriate cooling capacity to meet the different demands of the temperature and humidity of the test chamber on cooling capacity, improving the ability of environmental testing equipment to conduct temperature and humidity tests, especially suitable for low temperature and low humidity environment control. The display is clear and intuitive, with a strong three-dimensional sense. The programmable control system is flexible and convenient to operate, with stable performance, more efficient work, and flexible installation methods. It can be installed externally or embedded.
