( 48 x 96 mm low cost controller )

 DESCRIPTION

The Fuzzy Logic plus PID microprocessor-based temperature controller,
incorporate two 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.
