Company Profile for OPSIS AB

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, such as U.S. EPA, German TÜV and British MCERTS. 

OPSIS’ environmental monitoring systems are characterized by their reliability, durability and low maintenance costs; numerous references will vouch for this. 

OPSIS was founded in 1985, and is today represented on all continents through a network of subsidiary companies, distributors and other representatives. 

OPSIS management system is certified according to the standards ISO 9001, ISO 14001, ISO 27001, and ISO 45001. OPSIS has also an accredited ISO/IEC 17025 laboratory.
