• Augmenting Air Quality Monitoring Networks

OPSIS is a leading supplier of ambient air quality monitors and associated products and services, throughout the world. Already back in the 1980s, OPSIS developed its first air quality monitor based on the open-path DOAS measurement principle, where gaseous air pollutants are detected and monitored based on optical absorption in the ultraviolet wavelength region. The DOAS technology has ever since been the centre of OPSIS product portfolio, although the range of monitors has been extended to also include many other types of instruments such as tunable diode lasers, particulate monitors, and meteorological sensors. Today, OPSIS is a one-stop-shop for virtually any need you may have within ambient air quality monitoring (AQM); whether it’s about detecting traditional air quality indicators such as sulfur dioxide, ozone, nitrogen dioxide and PM10, or more specialized gases pertaining to actual or potential sources of air pollution such as petrochemical industries and other industrial production facilities. Combined with sensors for e.g. temperature, air pressure, wind direction, wind speed, solar radiation and precipitation, OPSIS can give you full knowledge and thereby control of the air you breathe. Ambient air quality monitors have been at the heart of OPSIS’ business for the past thirty plus years, and it will be so for many years to come
