Pollutants measuring systems
We design pollutant monitoring as a stationary or portable automatic measuring stations, which detect and record components of air pollution caused by traffic, thermo and energetic sources, chemical operation and secondary influences taking place in the atmosphere (when solar radiation affects primary pollutants). These automatic monitoring stations can be used in urban areas, on the border of hygienic protection zones in industrial areas or in an open space country. The measured substances include mainly: sulfur dioxide, nitrogen oxides, carbon monoxide, dust, ozone, carbohydrates, volatile organic substances, polyaromatic carbohydrates, and so on.
The above mentioned automatic measurements can be supplied with sampling of gas and dust particles for later analysis in the laboratory. ENVItech Bohemia s.r.o. delivers and maintains these devices produced in the Czech republic or abroad.
Our product range is very broad, therefore do not hesitate to contact us even if the device you are interested in is not mentioned here.

Analyzers AEROQUAL
Aeroqual is based on 20-year academic research and development of products in the areas of gas sensor materials and smart measuring techniques. The Aeroqual vision is to be fulfilled in the area of air quality monitoring systems (pollutants).
Samplers
After a significant decrease of sulfur reactants in pollution, dust aerosol became one of the most important polluting substances of the ambient air in Europe. Its concentration is watched mainly with respect to its negative effects on human health. The results of long-term epidemiological studies persuasively show a relation between exposition to aerosol and illnesses.
Dust aerosol is looked at from two aspects. One is its chemical consistency; the other is the size of individual particles. Which aspect to measure is a disputable and essential question. Even though it has been proven that negative health effects are associated with aerosols containing particles of the size of nanometers, in most European countries only TSP (Total Suspended Particle), i.e. overall sample of dust aerosol without particle differentiation, is measured.
Reference method for sampling and measuring PM10 is described in European rule 12341 (CEN, 1998), which is also a Czech technical regulation. Regulation states, that the reference measuring method must be based on sampling probe PM10 directly connected to a filter and a device for a flow control and subsequent gravimetric determined fraction PM10 mass caught at the filter.
