T9000 CODcr Water Quality On-line Automatic Monitor

Product Name:CODcr Water Quality On-line Automatic Monitor

Product modelT9000

Product brand:FLUIDINGS

Power supply voltage: 9~36VDC

Chemical oxygen demand (COD) refers to the mass concentration of oxygen consumed by oxidants when oxidizing organic and inorganic reducing substances in water samples with strong oxidants under certain conditions. COD is also an important index reflecting the degree of pollution of water by organic and inorganic reducing substances.

The analyzer can work automatically and continuously for a long time without attendance according to the site settings. It is widely used in industrial pollution source discharge wastewater, industrial process wastewater, industrial sewage treatment plant wastewater, municipal sewage treatment plant wastewater and other occasions. According to the complexity of site test conditions, the corresponding pretreatment system can be selected to ensure the test process is reliable,test results are accurate, and fully meet the needs of different occasions.


DESCRIPTION

Features:

Water samples, potassium dichromate digestion solution, silver sulfate solution (silver sulfate as catalyst can be added to oxidize linear aliphatic compounds more effectively) and concentrated sulfuric acid mixture heated to 175. The color of organic compounds in dichromate ion oxidation solution will change. The analyzer detects the color change and converts the change into COD value then output the value.The amount of dichromate ion consumed is equivalent to the amount of oxidizable organic matter, namely COD.
