Product details
Conception
ROC-8221 is a combined control instrument of a single-stage reverse osmosis controller and double-channel on-line conductivity instrument. It can perform the operational test, status control and the on-line monitoring of inlet water, producing water, the temperature of the water and desalinization ratio of the water quality conductivity, displayed by LCD large screen. The interface is friendly, menu-driven operation is used; multiple group parameter can be set and modified. The requirement of automatic operation of the multiple controlling ways of the reverse osmosis system can be met.
Single stage double channels RO controller used for conductivity monitoring and process program control .
