Temi2702 Electronic Expansion Valve Controller/Temperature and Humidity Controller

Adopt advanced PID control technology to precisely control the opening degree of the electronic expansion valve, provide appropriate cooling capacity to meet the different requirements of the temperature and humidity of the test chamber for cooling capacity, and improve the ability of the environmental test equipment to conduct temperature and humidity tests, especially suitable for Control in low temperature and low humidity environment. Clear and intuitive display, strong three-dimensional sense, flexible and convenient operation of programmable control system, stable performance, more efficient work, flexible installation methods, and can be installed externally or embedded.
