- AOWXMAOWCOD Manhole COD and BOD Analyzer
Measurement principle:
The probe part of the product is an organic matter sensor that works by spectroscopy. According to the absorption of ultraviolet light by organic matter, the important measurement parameters of soluble organic matter content in water are reacted with 254nm spectral absorption coefficient SAC254 (absorbance), which can be converted into COD/BOD and turbidity values under certain conditions. This method can realize continuous monitoring without any reagents.
Main features:
▶ measurement parameters: COD, BOD (calculated by 0.75COD), turbidity;
▶ sensor adopts direct immersion installation without sampling and pretreatment.
▶ sensor can also be towed floating plate;
▶ no need for chemical reagents, no secondary pollution;
▶ own cleaning scraper;
▶ response time is short, continuous measurement can be realized;
▶ use LED light source, small size;
▶ host adopts expansion screw kit to realize quick installation of wellhead;
▶ main machine adopts stainless steel shell, good anti-corrosion, waterproof and impact resistance;
▶ steel seal, no fear of temperature changes on the seal;
▶ supports multiple opening of the lid, does not affect the waterproof, easy to replace the battery on site;
▶ low self-loss battery allows the device to obtain longer battery life;
Application scenarios:
Continuous monitoring of organic matter loading in sewage in manholes and on-line monitoring of water quality in and out of sewage plants;
Continuous online monitoring of surface water, industrial wastewater, and fishery wastewater.
