Total phosphorus determination and total nitrogen determination were developed according to the published documents, and the measurement results were accurate and effective. COD adopts closed digestion colorimetry, total phosphorus adopts closed digestion colorimetry, and total nitrogen adopts closed digestion ultraviolet photometric absorption method. The instrument is widely used in environmental testing, sewage treatment, scientific research units and universities.
The heavy metal analyzer is a colorimetric analysis method based on the reaction of a sample to be reacted with a developer to form a colored compound that selectively absorbs electromagnetic radiation. The instrument is composed of a silicon light source, a lens, a colorimetric bottle, a photocell, and a signal microprocessor, and can directly display the content of ammonia nitrogen in the sample to be tested on the liquid crystal screen. The ammonia nitrogen detector is suitable for the detection of ammonia nitrogen concentration in large, medium and small water plants and industrial and mining enterprises, domestic or industrial water, in order to control the ammonia nitrogen of water to meet the specified water quality standards.
The black and smelly water body of the city is a common water environment problem reflected by the masses, which not only seriously affects the image of the city, but also seriously affects the health and happiness of the residents. In recent years, the efforts of urban black and odorous water treatment are increasing day by day
Environmental protection has always been a topic of common concern for the whole society. Environmental quality involves all aspects of human life and production: Food heavy metals exceed the standard, which may be related to soil pollution; drinking water does not meet the standard, which may be related to water environmental pollution
The Ministry of ecological environment recently issued the notice on collecting the units undertaking the projects of national ecological environment standard plan in 2020, which is responsible for the formulation of 49 ecological environment standards, including 1 environmental quality standard, 21 pollutant emission (control) standards, 16 environmental monitoring standards and 11 environmental management standards.
Exhibition time: June 12-14, 2019. Venue: Beijing International Exhibition Center. Booth No.: Hall 5 5527, 5529. We will bring: multi parameter water quality tester, portable multi parameter water quality tester, cod · ammonia nitrogen · total phosphorus · total nitrogen tester, cod · ammonia nitrogen · total phosphorus tester, cod · ammonia nitrogen tester, total phosphorus tester, total nitrogen tester and other upgraded new products.
