What data can be detected by the residual chlorine analyzer

by:BOQU     2023-03-31
When measuring with the residual chlorine analyzer, when the tested water sample drops into the o-toluidine reagent, the water sample will turn yellow, and then put the water sample into the photoelectric colorimetric seat. The instrument will obtain the concentration of residual chlorine by comparing the depth of yellow. The measuring instrument adopts DPD photometric method and photoelectric colorimetric detection principle to replace the traditional visual colorimetric method, which eliminates human errors and has high measurement resolution. When the chloride ions in the water react with the DPD reagent, the water sample will turn pink. Then put the water sample into the photoelectric colorimetric seat of the instrument, and the instrument can obtain the concentration value of the corresponding ion by comparing the color depth. It can be widely used in waterworks, industrial and mining enterprises, hospitals, domestic or industrial water inspection departments to control the concentration of ions in water to meet the specified water quality standards. The Chlorine Meter can be used to detect the following data: 1. Chromaticity: If the chromaticity of drinking water is greater than 15 degrees, most people can detect it. According to the standard, the chromaticity of drinking water must not exceed 15 degrees. 2. Turbidity: It is an expression of the optical properties of water samples. Used to indicate the clarity and turbidity of water. It is one of the important indicators to measure the quality of water, and it is also an important basis for evaluating the purification efficiency of water treatment equipment and evaluating the state of water treatment. The reduction of turbidity means that the content of organic matter, bacteria, viruses and other microorganisms in the water body is reduced, which can not only improve the disinfection and sterilization effect, but also reduce the generation of halogenated organic matter. 3. Residual chlorine: Residual chlorine refers to the amount of residual chlorine remaining in the water after the water has been chlorinated and exposed for a certain period of time. It has continuous sterilization ability in water, which can prevent self-pollution of water supply pipelines and ensure water quality. 4. Chemical oxygen demand (COD): refers to the oxygen required by chemical oxidants to oxidize organic pollutants in water. The higher the COD, the more organic pollutants in the water. Organic pollutants in water mainly come from the discharge of domestic sewage or industrial wastewater, and the flow of animals and plants into water bodies after decomposition.
