Features: This smart digital temperature controller uses advanced special chip for industrial instruments of high precision, strong anti-interference ability. High reliability, multi-type sensor input, using wide range switching power supply. It has the new fuzzy control combined with the advanced PID control algorithm, good control of rapid change and long lag time. Advanced non-overshoot self-tuning scheme for convenient use, also with communication function. The controller has small size and stable performance, easy to operate.
