General description :

CH short shell series intelligent (temperature) display regulator adopts 8-bit single-chip high reliability, a variety of sensors freely input, and it adopts a wide range of switching power supply. The product’s performance indicators, input style, control function and the installation size are fully compatible with the i mported intelligent digital temperature controller. CH short shell series intelligent meters, having the latest fuzzy control and combining with advanced PID adjustment algorithm, precisely control the controlled objects.
