ZEL-C Series Temperature & Process Controller

ZEL-C Series
Zesta ZEL-C62
Zesta ZEL-C62
The ZEL-C Seris is the newest generation of low cost PID microprocessor-based controllers.  Equipped with Fuzzy logic / PID control, this controller incorporates two bright easy-to-read LCD displays, indicating Process Value (PV) and Set Point value (SP).

The Fuzzy Logic technology incorporated on this controller enables a process to reach a predetermined set point in the shortest time with minimum of overshoot during start up or external load disturbances.
