OPSIS AB is the leading supplier of open-path monitoring systems for air quality monitoring, continuous emissions monitoring (CEM) and process control. OPSIS offers total monitoring solutions and the product line includes both monitoring hardware and data handling software. The DOAS technology, developed by OPSIS, has received international approvals and provides customers with reliable system solutions for a number of applications.
OPSIS AB is a globally present company that develops, manufactures and markets state-of-the-art, innovative systems for gas analysis and process control. Our goal is to provide our clients with a total monitoring solution, including reliable and cost-effective systems, regardless of applications. Systems are available for ambient air quality monitoring (AQM) and continuous emissions monitoring (CEM)/process control. Thousands of our systems are running worldwide. By focusing on our customers’ requirements and on continuous research and development, OPSIS continues to lead the way and set the standard in gas monitoring.
OPSIS was founded in 1985, and is today represented on all continents. A network of subsidiary companies, distributors and other representatives, has been established, that are among the most competent and experienced organisations in each of the countries where they are operating.
To ensure that operators get the best results, we provide thorough training courses for successful monitoring operation, calibration and maintenance. The courses are custom-designed in order to suit each operator’s needs and requirements. Also, we continuously arrange technical training courses for our distributors and representatives in order to guarantee thorough knowledge about our monitoring systems.
- Provide monitoring data with lowest possible environmental impact
- Provide monitoring data with certified quality
- Provide more monitoring data at less cost
OPSIS is a global supplier of environmental monitoring systems for gas analysis and related services. OPSIS has provided thousands of systems both for ambient air quality monitoring (AQM), for continuous emissions monitoring (CEM), and for process control applications. The OPSIS systems are sold and serviced world-wide through a network of distributors and other representatives.
OPSIS’ first focus area was gas detection in ambient air using a novel open-path technology called DOAS. It soon evolved to use the same technology also in industrial applications such as emissions monitoring in power plants and for process control in production facilities. Other types of gaseous and particulate detectors as well as other application-specific sensors were also added to the product portfolio, resulting in today’s wide range of environmental monitoring equipment and related products and services.
Presently, OPSIS has about half of its business in the AQM field, and half of it in the CEM/process control field. The central monitoring equipment is almost always a DOAS analyser, operating either in the ultraviolet (UV) or the infrared (IR) wavelength region. The analyser is combined with other types of sensors and communication solutions, resulting in a complete environmental monitoring system.
A typical OPSIS system for AQM consists of a UV DOAS gas analyser, a beta attenuation dust monitor and a set of meteorological sensors, monitoring local air quality. Multiple AQM systems are often combined in networks allowing full surveillance of the air in larger regions. The measurement results are usually forwarded to data management systems over the Internet. This allows for real-time presentation of air quality as well as statistical analysis and air quality studies that can help improve the quality of the air we breathe.
A typical CEM/process control system consists of one or two DOAS analysers (UV + FTIR) for measurements of gas concentrations, in combination with other instruments providing e.g. flue gas flow rates and dust concentrations. The measurement results are often forwarded in real time to the process control system using any of the standard industrial communication protocols supported. From there, the results can be used for e.g. emissions monitoring and process optimization.
OPSIS’ environmental monitoring systems have been tested and approved by a number of internationally recognized institutes and authorities.
OPSIS’ environmental monitoring systems are characterized by their reliability, durability and low maintenance costs; numerous references will vouch for this.
