Reverse Osmosis Controller CCT-8320 is a combined control instrument of a single-stage reverse osmosis controller and double-channels 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.
Main Specification:
I.            LCD big screen with backlight, monitor and display double-channel conductivity (conductivity of the one-grade producing water and inlet water) at the same time, Temperature of the medium, desalinization can be displayed on the same screen. The measurement range of the conductivity of the producing water  0～20.00、0～200.0（μS/cm）can be switched automatically.
II.          Intelligent microchip for data processing, friendly and easy operation interfaces; menu-style operation, multiple parameters needed can be inputted or modified; kinds of requirement can be satisfied. Multifunction, simply operation, supports kinds of executors and running modes.
III.         Three protections (dampness, static, rot) make the controlling system strongly enough to endure the high damp and rugged environment. Test ports of the reverse osmosis controller adopt low pressure up-draw electrical bit. Photoelectricity input isolated, high anti-jamming capability. reference point adopts passive output to drive the contact device directly.
IV.         RS485 isolated data interface, standard Modbus communication agreement (RTU), connecting with PLC, epigyny device configuration expediently, epigyny device can send reading orders. of the inflow water conductivity , output water conductivity, controlling status of the relay, alarm input status and system running status, baud rate 2400,4800,9600 can be set by keyboard.
