COD water quality detector, a professional instrument for analyzing the content of water quality components, measuring water: an instrument for COD projects. In order to protect the water environment, it is necessary to strengthen the monitoring of sewage discharge. The quality of drinking water is declining, which is extremely harmful to human health. Water quality detectors play an important role in environmental protection, water quality detection, and water resources protection.
The principle of COD water quality detector:
The organic matter in the water sample is oxidized by potassium dichromate in the presence of sulfuric acid, silver sulfate, and mercury sulfate to produce carbon dioxide and water. The amount of potassium dichromate used is calculated from the difference in the volume of ammonium ferrous sulfate consumed in the titration of the blank and the sample. The amount of potassium dichromate used in the reaction is equal to the oxygen used to oxidize the organic matter in the wastewater.
Product display of COD water quality detector:
It can be used to determine the turbidity, chroma, suspended matter, residual chlorine, total chlorine, compound chlorine, chlorine dioxide, dissolved oxygen, ammonia nitrogen, nitrite, chromium, iron, manganese, copper, nickel. Zinc. Sulfate. Phosphate. Nitrate Nitrogen. Anionic detergent. COD and other parameters. At the same time, 3 blanks are reserved for users. Users can calibrate and use in the form of percentages according to their own requirements, which provides convenience for customers. This instrument can be widely used in sewage detection in water plants, food, chemical, metallurgy, environmental protection, and pharmaceutical industries. It is a commonly used laboratory instrument.
