    • AOWXM/AOWCOD manhole CODBOD analyzer

    Measurement principle:

     

    The product probe is an organic matter sensor that operates using spectroscopy. Based on the absorption of ultraviolet light by organic matter, it uses the 254nm spectral absorption coefficient SAC254 (absorbance) to reflect the important measurement parameters of soluble organic matter content in water, and can be converted into COD/BOD and turbidity values under certain conditions. This method can achieve continuous monitoring without the need for any reagents.

     

    Main features:

     

    ▶  Measurement parameters: COD, BOD (calculated based on 0.75COD), turbidity;

     

    ▶  The sensor adopts direct immersion installation, without sampling and preprocessing;

     

    ▶  Sensors can also be towed by floating plates;

     

    ▶  No need for chemical reagents, no secondary pollution;

     

    ▶  Comes with a built-in cleaning scraper;

     

    ▶  Short response time, capable of continuous measurement;

     

    ▶  Using LED light source with small size;

     

    ▶  The host adopts an expansion screw kit to achieve quick installation at the wellhead;

     

    ▶  The host adopts a stainless steel shell, which has good anti-corrosion, waterproof, and impact resistance performance;

     

    ▶  Steel seal, not afraid of the influence of temperature changes on the seal;

     

    ▶  Supports multiple lid openings without affecting waterproofing, making it easy to replace batteries on site;

     

    ▶  Low self loss batteries enable devices to achieve longer battery life performance;

     

    Application scenarios:

     

    Doppler flow meter brings you professional service,continuous monitoring of organic load in sewage from manholes and online monitoring of inlet and outlet water quality in sewage treatment plants;

     

    Dopple flow meter brings you professional service,continuous online monitoring of surface water, industrial wastewater, and fishery wastewater.
