Ambient stations for ambient air quality monitoring - Air and Climate - Air Monitoring and Testing

Ambient air monitoring involves the measurement of `representative` air in urban, industrial and rural areas. These measurements are used to determine the human exposure to pollutants and can be combined with trace/background monitoring.

Ambient air quality monitoring at airports - Aerospace & Air Transport - Airports

To measure the ambient air quality at airports is a challenge. The monitoring site needs to be representative for background levels and not dependant on changes in local traffic. A large number of gaseous components need to be measured with high accuracy and high availability. The OPSIS DOAS system provides the user with a fast system that gives high availability at low cost. The impact of aircraft take-offs and landings can easily be followed on-line. The OPSIS system can also monitor fugitive emissions from ...

Ambient air quality monitoring solutions for PM2.5/PM10 particulate monitoring - Air and Climate - Air Monitoring and Testing

OPSIS provides real-time, flexible monitoring of particulate matter in the ambient air. Particulate matter monitoring with OPSIS, is a cost-effective solution, is ideally suited for use in modern monitoring stations. It can be remote controlled and includes automatic calibration, features that frees time. The SM200 meets the new regulation for automatic monitoring of PM10 and PM2.5. It also meets the new regulation for particulate matter sampling on filter membranes for further analysis of cadmium, nickel, PAH and ...

Ambient air quality monitoring solutions for remote sensing of ship emissions - Shipbuilding & Water Transport

New regulation forces ships to lower the emissions of SO2. Ships travelling in SECA areas has to either run on low sulphur fuel, or install SO2 scrubbers. To measure the SO2 emissions from a ship is not an easy task. OPSIS provides the Port Authorities with a unique measurement principle where the emissions from the ship is measured remotely. Light is passing the emissions and by analyzing the light, concentrations of SO2 can be measured.

Ambient air quality monitoring solutions for street-level monitoring - Environmental - Environmental Monitoring

To measure the air quality in a city is a challenge. A large number of gaseous components need to be measured with high accuracy. The monitoring site needs to be representative for the city and the system has to be easy to maintain and calibrate. The OPSIS open-path monitoring systems provide a flexible solution, giving the average concentration for an area. A single OPSIS system can measure all relevant gaseous components set by the authorities, such as NO, NO2, SO2, O3, BTX, NH3.

Ambient air quality monitoring solutions for tunnel monitoring - Monitoring and Testing - Environmental Monitoring

Car tunnels need ventilation in order to keep air pollution below the limits. When the pollution levels reaches a setpoint, the fans must be started and kept running until the pollution levels decreases.

Ambient air quality monitoring solutions for urban air quality monitoring - Air and Climate - Air Monitoring and Testing

To measure air quality in the ambient air is a challenge. The monitoring site needs to be representative and not dependant on changes in local traffic. A large number of gaseous components need to be measured with high accuracy and high availability.

Ambient air quality monitoring solutions for benzene fence-line monitoring - Air and Climate - Air Monitoring and Testing

To monitor benzene emissions can be a challenge, but OPSIS makes it easy. Benzene is an aromatic hydrocarbon liquid that evaporates quickly if exposed to ambient air. It is one of the most commonly used substances in the chemical industry and it is known to cause cancer. For this reason, refineries in the United States must start monitoring fugitive emissions of benzene from January 30, 2018. This is part of the 2015 U.S. EPA Petroleum Refinery rule. In case a yearly rolling average of benzene concentrations ...

Air Quality Monitoring Network Contract Awarded to OPSIS

OPSIS AB has been commissioned by Kuwait Oil Company (KOC) to assess the impact of KOC:s operations in the state of Kuwait. A network of air quality monitors will be managed. Emissions to the air from KOC:s operations will be reported. A dispersion model will be used to determine the impact from KOC:s operations to the air quality in Kuwait. The project will continue for five years.
