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 372
The APDA-372 dust monitor is specifically designed for indoor and outdoor air quality measurements and provide continuous and simultaneous measurements of PM1, PM2.5, respirable fractions (PM4), thoracic fractions (PM10), inhalable fractions (TSP), the particle number, and (upon request) the particle size distribution in 32 size classes per decade within the particle size range of 0.18 – 18 µm. The APDA-372 uses the recognized measurement technology of optical light scattering and is equipped with a white LED light source with highly stable output and long lifetime. The system is also equipped with a filter holder for the insertion of an absolute filter (47 or 50 mm in diameter). This enables the user to perform on-site gravimetric correlation or subsequent analysis of the composition of the aerosol. The APDA-372 can be connected to an isokinetic sampling probe that measures emissions in exhaust air ducts. The volume flow is 5 L/min. The APDA-372 is additionally equipped with sensors for measuring environmental conditions, such as temperature, atmospheric pressure, and relative humidity.
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.

- Collect data from Ambient Air Monitoring Stations
- Manage and store collected data
- Provide reports based on stored data
The I/O Expander takes as a central component of the Immission measuring station the calculation of averages, controlling function controls and saving data. The raw data are analogue, serial or read in via Ethernet. Automatically when certain events occur, a message by SMS or e-mail will be sent. The transmission of measurement data in the control centre is via a modem or network. For configuration and visualization software IOVIS Lite is included.
