Ambient Air Quality Monitoring System
Air pollution is one of the most serious global and regional environmental problems. A major source of air pollution is industrial activities, including oil industries and power generation and vehicles. These pollution sources are associated with the emission of polluting gases such as carbon oxides, sulphur, nitrogen oxides, hydrocarbons, volatile compounds, as well as with the emission of particular matter and heavy metal elements. The Air Quality Monitoring systems that we provide enables the local authority to apply internationally approved standards in monitoring air pollution, to preserve the environment and public health from the effects of pollution sources emissions in a certain area, to take preventive measures to reduce the risks of this pollution.

Dust analyser ‒ Horiba APDA 371
Particulate matter contaminates our atmosphere in various ways. It can for instance be generated by different industrial production processes,waste combustion, coal mining or automobile exhausts. The APDA-371 automatically measures and records airborne particulate concentration levels (in milligrams or micrograms per cubic meter), using the industry-proven principle of beta ray attenuation. Each hour, a small carbon-14 element emits a constant source of high-energy electrons (known as beta rays) through a spot of clean fillter tape. These beta rays are detected and counted by a sensitive scintillation detector to determine a zero reading. The APDA-371 automatically advances this spot of tape to the sample nozzle, where a vacuum pump then pulls a measured and controlled amount of dust-loaded air through the filter tape. Hourly this dirty spot is placed back between the beta source and the detector thereby causing an attenuation of the beta ray signal which is used to determine the mass of the particulate matter on the filter tape.
The APDA-371 Air Pollution Dust Analyzer for Suspended Particulate Matter (SPM) ensures long term stability and self-diagnostic capabilities as well as efficient collection of fluorine resin tape. The measurement principle operates according to EU and EPA regulations and is also type approved by TUV.
