    OTA WiFi Digital COD Analyzers Water Quality COD Measurement Instrument


    OTA WiFi Digital COD Tester Water Quality COD Measurement Instrument


    Brief Introduction


    • High COD means that the water contains a lot of reducing substances, mainly organic pollutants. The higher the COD, the more serious the organic pollution in the water. The source of organic pollution may be pesticides, chemical plants, organic fertilizers, etc. If not treated, many organic pollutants can be adsorbed and deposited on the bottom of the river, and then cause lasting toxic effects on aquatic organisms;

    • The DUC2-COD-S-D COD measurement instrument can simultaneously meet the needs of users for detection, control, and remote data transmission, with rich output settings;

    • 2 high-precision 0/4~20mA current outputs with a maximum load of 1000 ohms;

    • 2 settable SPST multifunctional relays with a maximum load of 3A/250V AC;
    • The enclosure protection grade is IP66, can effectively isolate the pollution and corrosive gas from the external environment;

    • The COD tester has a two-wire RS485 interface, the communication protocol is MODBUS RTU, and supports JSON text data format;

    • The shell material of the analyzer is enhanced ABS, its overall size is 144*144*120mm;
    • Its operating environment is 0~60℃, relative humidity is less than 95% (non-condensing); its storage environment is -20~70℃, relative humidity is less than 55% (non-condensing);

    • DUC series COD tester can meet a variety of installation methods, such as wall-mounted installation, pipe clamp installation, panel installation, and provide accessories required for installation.


    Advantages Of The COD Tester


    • Menu password can be set to facilitate user's data confidentiality;

    • Clock and historical data recording function, which can record 14,000 historical data, and the recording interval can be set between 1 and 999 minutes.

    • 3.2-inch display screen and a 128*64 black and white graphic dot matrix LCD liquid crystal display, with reasonable interface settings and simple operation;

    • The COD analyzer has a power-off protection configuration, and the parameters can be kept indefinitely;
    • The display backlight of this instrument provides a choice of always-on and energy-saving modes, which users can set according to their needs;

    • The connected sensors upload the detected data in a special encrypted communication method to ensure that the DUC controller can collect high-precision data in a more stable manner.

    • This controller is equipped with OTA download technology, using wifi; GSM; CDMA, and other wireless technologies to realize remote software upgrades, fault diagnosis, and assistance in instrument parameter configuration for customers. It not only reduces the workload of on-site service of the instrument but also minimizes the time that users wait for service.
