Summary:
CH402 Temperature Indicator Thermoregulator with PID control  is the new product developed by our company. It adopts special microcomputer adjusting meter that employs switching power and surface mount technology(SMT), therefore, the controller is quite smart and reliable. Its special functions like auto diagnosing, auto setting and intelligent control. It can be used widely in the display and controling of the parameter of the temperature pressure, flow, and liquid level.
