Applicable for the automatic control and monitoring of reverse osmosis plants with flexible programmable software so this controller is suitable for a large number of various water treatment plants.

RGS8000 for automatic control and monitoring of reverse osmosis plants. With flexible programmable software for various water treatment applications.


The unit type RGS8000 is universal applicable for automatic monitoring and control of reverse osmosis plants. The controller, what comes in a choice of four possible different languages, has seven outputs and eight inputs. Adaptable to user specific requirements due to additonal options like up to four conductivity meters with temperature control, up to six recorder outputs, ethernet communication , RS232 and RS485 communications and by built-in programmable options. The programmed configuration will be stored into non volatile memory and therefore not be affected by power loss.
