     DR-103A CODcr water quality online automatic monitor
     
    Introduction:
    The instrument adopts potassium dichromate oxidation-spectrophotometry, which conforms to the "Chemical Oxygen Demand (CODCr) Water Quality Online Automatic Monitor" (HJ377-2019), which ensures the accuracy and validity of the monitoring data.
    The combination of the classic potassium dichromate high-temperature digestion and oxidation method and the dual optical path test technology reduces the detection limit of the traditional method and improves the measurement accuracy. In addition to the traditional pollution source monitoring, it can also be used for ultra-low concentration CODCr in surface waters such as rivers and lakes. Measurement.
    The instrument is miniaturized, standardized, and portable. It can be installed on the desktop in the station room, installed in the standard cabinet, installed in the monitoring vehicle, and used flexibly and portable for emergency monitoring.
    DR-103A CODCr water quality online automatic monitoring instrument can be used for laboratory self-testing during internal control of sewage treatment plants and sewage enterprises, online monitoring of general discharge supervision departments, and high-precision online monitoring of low concentration of surface water.
    Features:
    1. The lower limit of measurement is low, the test results are accurate, and it has very good consistency with the laboratory;
    2. Small in size and flexible in installation, it can be used as an automated device for rapid COD measurement in the laboratory;
    3. Calibration: automatic calibration, manual calibration, remote calibration;
    4. Measurement: manual measurement, timing measurement, periodic measurement, intermittent measurement, remote measurement;
    5. Signal transmission: switch value, (420)mA, RS232, RS485;
    6. Data export: data can be exported through U disk;
    7. System maintenance: emptying the system, cleaning the metering tube, cleaning the digestion tank, and manual testing of key components;
    8. Abnormal alarm: fault alarm, reagent shortage pre-alarm;
