Brainchild C22 Temperature Controller with 2 LCD Display

Description

Brainchild C22 Temperature Controller with 2 LCD Display The new generation low-cost PID microprocessor-based Fuzzy logic digital controller series incorporates two bright easy-to-read LCD Displays that indicate Process value (PV) and Setpoint value (SP). The Fuzzy Logic technology incorporated into this series controller enables a process to reach the predetermined set point in the shortest time with a minimum overshoot during Start (Power ON) or external load disturbances.
