MIXED BED CONTROLLERS EC3020
The unit type EC3020 is universal applicable for automatic monitoring and control of single or twin mixed bed cartridge filters where filter cartridge should be exchanged by hand. The controller is equipped with a conductivity meter without temperature meter. Adaptable to user specific requirements by built-in programmable options. The programmed configuration will be stored into non volatile memory and therefore not be affected by power loss.
