Product details and functions of COD water quality detector

by:BOQU     2022-03-10

COD water quality detector, a professional instrument for analyzing the content of water components, measuring water: the instrument for the COD project. In order to protect the water environment, it is necessary to strengthen the monitoring of sewage discharge. The decline of drinking water quality is extremely harmful to human health. Water quality detectors play an important role in environmental protection, water quality testing and water resources protection.

COD water quality detector principle:

Organic substances present in water samples are 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 was calculated from the difference in volume of ferrous ammonium sulfate consumed in the titration of blank and sample. The amount of potassium dichromate used in the reaction is equal to the oxygen used to oxidize wastewater organics.

COD water quality detector product display:

It can be used to measure turbidity, chromaticity, suspended solids, residual chlorine, total chlorine, combined chlorine, chlorine dioxide, dissolved oxygen, ammonia nitrogen, nitrite, chromium, iron, manganese, copper, nickel in sewage. Zinc. Sulfate. Phosphate. Nitrate nitrogen. Anionic detergent. This instrument can be widely used in sewage detection in water plants, food, chemical industry, metallurgy, environmental protection and pharmaceutical industries. It is a commonly used laboratory instrument.
