The Reverse Osmosis Controller (RO Controller) CCT-7320 is a combined control instrument of a reverse osmosis controller and an on-line conductivity meter. The RO controller can perform the operation test, status control and on-line monitoring of water quality conductivity (combining PLC controller and conductivity meter). It takes multiple anti-interference measures, adopts unique process flow and graphical control panel with LED indicator lamp embedded, the interface is friendly; menu-driven operation is used, multiple groups of parameters can be set and modified, the requirements of automatic operation are met. Process Flow Selections There are two typical operation modes for RO system (as shown in Fig.1A and B). This instrument can operate in both modes in A and B. Technical Specifications: 1. Power voltage: AC 220V±15% 50Hz Power consumption: ≤3W 2. Environment conditions: 1) temperature: 0～50℃; 2) humidity: ≤85%RH 3. Measuring range: 0～20μS /cm，0～200μS /cm，0～2000μS /cm （Fixed range which has been set by the manufacturer and can not be changed by customers: Please indicate which measure range will be needed before placing an order. 200μS /cm or 2000μS /cm ? The ex-factory standard is 0-200μS /cm without prior indication. Except the range, please also let us know you need high pressure flush or low pressure flush program before placing an order） Note: 0～2000μS /cm is suitable for the equipment with conductivity of the outflow water 100～2000μS /cm, with conductivity lower than 100μS /cm, measure range 0～200μS /cm or 0～20μS /cm should be selected. Accuracy: 1.5 level 4. Load capacity of output contact: 3A/250V AC (the magnetic valve should be driven through intermediate relay) 5. Operation pressure of conductance cell: 0～0.5Mpa 6.Medium temperature:5～50℃ 7.Temperature compensation: automatic temperature with 25℃ as reference temperature 8. Distance of measuring range: less than 30m (the ex-factory configuration of electrode cable is 5m unless there is a special agreement) 9. Display mode: 3 1/2-digit LED digital display 10. Electrode selected: 1.0cm-1 11. outline dimensions: 96×96×110mm (height×width×depth) meter board hole: 92×92mm (height×width)
