Currently, most of the changes in COD in sewage are monitored in real-time using online detectors, which can quickly detect changes in organic pollutants in the water body, and can be immediately treated in case of problems to prevent worsening of water p

Residual chlorine is one of the important indicators in the testing of hospital sewage. As a complex water quality situation, there are strict national standards for the discharge of hospital sewage. Generally, the generated sewage needs to be disinfected

If you want to know the measuring principle of COD tester, you should first understand what COD is. COD is the abbreviation of Chemical Oxygen Demand, which is a method to measure organic pollutants in water. Organic substances in water samples are oxidiz

In recent years, with the continuous improvement of peoples awareness of environmental protection of the water environment, the national supervision and management of the water environment has become more and more strict. In order to make the sustainable

Turbidity is one of the important parameters in water quality detection. It mainly refers to the concentration of suspended substances and particles in water. It is usually measured by colorimetry or laser scattering method, and the unit is NTU. Why is tu

Online water quality detector as a continuous monitoring of water quality equipment, can measure various parameters of water quality. Such as pH, temperature, dissolved oxygen, turbidity, conductivity, ammonia nitrogen, total phosphorus, total nitrogen, e

Generally, the online cod detector is mainly used for monitoring various industrial wastewater such as sewage treatment, aquaculture, petrochemical, coking and so on, as well as monitoring livestock domestic sewage and leachate from garbage sites; And CDO

Detection principle Generally, the cod detector is used to determine the concentration by spectrophotometry, which is detected by sampling, dosing, digestion and other processes. Its principle is to rapidly catalyze the oxidation-reduction reaction of

The analytical method of conductivity water quality detector is to put the measured solution in a conductivity cell composed of two platinum electrodes with a fixed area and a fixed distance, and determine the content of the measured substance by measurin

The swimming pool water quality test items include: turbidity, ph, pH, urea solution, mineral acid residual chlorine, combined residual chlorine, bacteria number, total coliform group, ozone, temperature, total dissolved solids, oxidation-reduction potent
