Our complete range - Low-cost PID controllers


The Fuzzy Logic plus PID microprocessor-based temperature controller, has two rows of 4-digit LED digital display in its panel, which can display process value and set value at the same time. 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 electronic temperature control and PID controller.
