Indoor air pollutants are among the top five environmental threats to human health ,highlighting the need of ensuring acceptable indoor air quality in buildings. Numerous things, such as smoke, microbes, volatile organic compounds, and gases like carbon monoxide and carbon dioxide, can impair the quality of the air inside a building. Humidity can also harm building components, raise heating and cooling costs, and encourage the growth of bacteria and mold, which can aggravate allergies and respiratory issues. Specialists in air quality can gather information about internal circumstances through monitoring, pinpoint problem sources, and develop mitigation strategies. Monitoring can also be used to check on the effectiveness of remedies.

Maintenance of ِAmbient Air Stations

  • The maintenance and operation of automatic measurement systems is one of our main activities.

  • All Air Quality Monitoring Station (AQMS) must be maintained according to the manufacturer’s recommendations. We provide services for routine and/or periodic service maintenance visits for all major brands of air quality monitoring instrumentation.

  • We believe in the empowerment of our clients. We provide training for the operation and maintenance of all ambient air quality monitoring instrumentation and systems. Clients are provided with all materials required for the management of the station including maintenance schedules and checklists.


The only way forward, if we are going to improve the quality of the environment, is to get everybody involved
