Description :

　　1) The system integrates water quality monitoring sensors, data processing units, and internal water flow pipeline units into one, with an integrated design and small space occupation;

　　2) Can continuously measure temperature PH、 Turbidity and disinfectant indicators (residual chlorine/total chlorine/ozone), expandable parameters such as conductivity, TDS, ORP, DO, etc., can be connected to up to 7 instruments simultaneously, displaying 8 parameters;

　　3) Scalable access to any brand of standard MODBUS RS485 output sensors or instruments, such as support for accessing data from MODBUS RS485 output flow and pressure instruments;

　　4) Disinfectant indicators can be selected based on various principles such as DPD colorimetric method, constant voltage method, membrane method, etc;

　　5) The DPD colorimetric method for residual chlorine/total chlorine has an automatic cleaning function for the colorimetric dish, greatly reducing maintenance and improving the stability of measurement data;

　　6) The turbidity adopts the EPA principle of 90 ° scattered light technology, which can ensure the accuracy and stability of low turbidity. The light source adopts LED light source, which has low power consumption and long light source life;

　　7) The internal wiring and waterway integration are high, and users only need to connect the power supply and water inlet and outlet, making on-site installation of the equipment convenient;

　　8) The internal waterway design can ensure stable water flow during the internal measurement process of the equipment and ensure accurate monitoring data;

　　9) Adopting a 7-inch color touch screen, the operation interface is simple, easy for users to learn, the system is reliable, and the maintenance is low;

　　10) Equipped with automatic fault diagnosis function, with abnormal information recording and uploading function, such as component failure, over range alarm, over limit alarm and other information;

　　11) Has three-level password permission management;

　　12) It has data storage function, and the data can be displayed in the form of tables and curves, which can intuitively and accurately understand and track the changes of water parameters within a certain period, and can realize the download of historical data;

　　13) It has a time display function and can set, calibrate, and display parameters for time;

　　14) It should have power-off protection and automatic recovery function for incoming calls;

　　15) Built in wireless data transmission module, realizing data collection and wireless data transmission functions;

　　16) Built in turbidity sensor power supply with reverse polarity protection; Sensor RS485 A/B terminal misconnected power protection;
