The Fuzzy Logic plus PID microprocessor-based temperature controller, incorporate one bright, easy to read 4-digit LED display, indicating process value and set point value. The Fuzzy Logic technology enables a process to reach a predetermined set point in the shortest time, with the minimum of overshoot during power-up or external load disturbance.

As a professional and experienced manufacturer, we supply high-performance and quality temperature controllers, which are also called temperature control, electronic temperature control, electronic temperature controller, and PID controller.
