Water Monitoring and Testing
Industrial and municipal wastewater monitoring solution

Emissions of urban wastewater is big in a lot of industries in China, it has caused serious pollution of city surface water. The environmental monitoring center of the city shoulder monitoring work of urban surface environment water and pollution discharge wastewater. the on-line monitoring system is established in order to improve the water quality monitoring capacity. waste water system built an urban wastewater monitoring network system which consists of sewage monitoring station, monitoring...
Surface water and water conservancy monitoring solution

Surface water and water conservancy monitoring is an important foundation work for reasonable utilization and protection of the nation water and soil resources, is a foundation of science management and protection of water ecology, water resources, water safety. The purpose of water quality monitoring is timely, accurate and comprehensive reflection of water environment quality present situation and developing trend, providing scientific basis for water environment monitoring, management, planning,...
Rural domestic sewage monitoring

Due to dispersion of regional, large population quantity, difficult collection, rural sewage becomes the main form of water pollution factors. Rural sewage contains a lot of organic matter and inorganic salts such as nitrogen, phosphorus, etc.
Air Monitoring and Testing
Flue gas denitration on-line continuous monitoring solution

Nitrogen oxide (NOx) is one of the main sources of air pollution, not only it has significant influence on global warming, but also involved in the destruction of the ozone layer. Technical measures to control NOx emissions can be divided into two categories: one is so-called source control, the characteristic is by a variety of technical means, to control NOx generation in the process of combustion reaction (i.e., low NOx combustion technology). Another kind is the so-called tail control, the...
Atmospheric VOC online monitoring solution

VOCS are volatile organic compounds, according to their chemical structure it can be divided into alkanes, aromatic hydrocarbons, esters, aldehydes, etc. The most common type of gas composition are benzene, toluene, xylene, styrene, trichloroethylene, chloroform, trichloroethane, diisocyanate (TDI), two different cyanide methyl ester, etc. the gas is discharged in industries such as the spray paint, petrochemical, chemical, shoes, printing, electronics, clothing dry cleaning, oil, construction,...
Dust on-line monitoring solution

With the application of air quality PM2.5 standards, people have a clear understanding and attention on ambient air quality, countries also present clear requirements and control objectives. Due to the speeding up of development process of cities construction in recent years, unceasing expands of the urban area and population scale, sustained growth of energy demand, motor vehicle ownership, various construction projects, the situation of urban air quality improvement work is more severe.

Monitoring and Testing
Flue gas heavy metals on-line continuous monitoring solutions

According to US EPA IO - 3.3 standard method of heavy metals, flue gas heavy metals analyzer uses XRF nondestructive testing technology and flue gas automatic enrichment technology to realize the accurate measurement of flue gas heavy metals such as waste incineration plants, cement plants, thermal power plants, etc.
Desulfurization on-line continuous monitoring solution

SO2 is one of several important pollutants in the atmosphere, SO2 from the atmosphere can stimulate people`s respiratory tract, abate respiratory function, and lead to respiratory resistance decreased, induce various inflammation of respiratory tract, harm to human health. SO2 also is harm to many plants. SO2 and its generated sulfuric acid mist can corrode metal surfaces and cause damage to paper products, textiles, leather products. It may also form acid rain, which is serious harm to the ecologica...
Metallurgical industry online monitoring solutions

Poorly controlled the concentration of gases such as CO, CO₂, CH₄ in the metallurgical industry cause poisoning, explosions and other accidents, and pose a serious threat to the safety in production. So it is essential to check the content of these gases for energy conservation, increase productivity, reduce energy consumption and protect the safety of life and product. The company`s gas analysis technology can accurately and reliably measure various...
