48 x 48 mm low cost and single display controller (C91)

DESCRIPTION
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.
