Chemical oxygen demand (COD) is a chemical method to measure the amount of reducing substances that need to be oxidized in water samples. Oxygen equivalent of substances that can be oxidized by strong oxidant in wastewater, effluent from wastewater treatment plant and polluted water.
Wtf2000-codcr COD on-line water quality analyzer adopts the national standard fast digestion spectrophotometry for analysis, the detection range standard is 0-1000mg / L, and the range can be expanded according to the actual water sample on site (the chloride ion concentration shall not be higher than 1000mg / L). In the strong acid medium, silver sulfate was used as catalyst, after rapid digestion at high temperature and high pressure, the reagent was added for spectrophotometric measurement.
·The fast digestion module is used for digestion, and the time can be set (10 to 30 minutes);
·Infrared measurement design, accurate measurement;
·The quantitative analysis module is designed with small specifications, which saves reagents and reduces maintenance workload;
·Dynamic visualization, intuitive and convenient operation;
·Remote read and write data, support remote calibration and calibration;
·The software adopts hierarchical password management to ensure safe use;
·The instrument is equipped with automatic cleaning function and automatic calibration function;
·The external interface is reserved, and the expansion function can be customized according to the site conditions;
