Opsis AB

What Opsis AB does

Opsis AB is a Swedish founder-owned instrumentation company, established in 1985 in Lund by Leif Unéus and Svante Wallin, that designs, manufactures and services systems for ambient air quality monitoring and industrial emissions analysis. The company is headquartered in Furulund, Sweden, operates two wholly-owned regional subsidiaries in Germany (OPSIS GmbH) and the United States (OPSIS, Inc.), and reaches more than 50 countries through a vetted distributor network. Its core technology platform is Differential Optical Absorption Spectroscopy (DOAS), complemented by Tunable Diode Laser (TDL), FTIR-DOAS, UV-DOAS, zirconium dioxide and beta absorption methods, enabling simultaneous multi-gas measurement along open optical paths and in extractive configurations for compounds such as SO2, NO2, O3, HF, H2S, TRS, dioxins, mercury, benzene and oxygen.

The product portfolio spans the System 400 multi-configuration platform, the LD500 laser diode analyser, the M800 marine system, the DX100 long-term dioxin/CO2 sampler, particulate monitors, real driving emissions monitors and turnkey monitoring stations, with the LiquidLINE and Liquid Monitoring sub-brands extending coverage into laboratory wet chemistry. Opsis monetises through a hybrid mix of capital-equipment sales, ISO/IEC 17025 accredited calibration and service agreements, installation and integration work, training, consultancy, and recurring cloud-based monitoring and data-validation services, with custom quotation-based pricing and multi-year contracts typical for industrial and government buyers.

The customer base is intentionally diversified across environmental authorities and regulators, heavy industrial operators (cement, aluminium smelters, pulp mills, waste-to-energy, chemical, refining, steel, fertiliser, glass, brick, mineral wool), maritime shipping (MARPOL/IMO scrubber and emissions monitoring), and the company's own distributor channel. The business is supported by an unusually broad certification stack (U.S. EPA, UK MCERTS, TÜV, Bureau Veritas, DNV, Lloyd's Register, RINA, Swedish EPA, Chinese CCAEPI and CCS, Indian NPLI CS, plus ISO 9001/14001/27001/45001/17025 and Achilles Sustainability), which constitutes the principal barrier to entry in regulated tenders.

Core offering

Opsis AB develops, manufactures and markets innovative optical spectroscopy-based systems for ambient air quality monitoring, industrial emissions monitoring, and process control. Its products use DOAS (Differential Optical Absorption Spectroscopy), tunable diode laser (TDL), FTIR-DOAS, zirconium dioxide and beta absorption technologies to measure trace gases and particulate matter in air, flue gases, and process streams. The portfolio covers turnkey monitoring stations, gas analyzers, particulate monitors, oxygen monitors, marine emission systems, and dioxin/CO2 samplers, complemented by installation, calibration, cloud data services and consultancy.

Product overview

Opsis AB develops, manufactures, and sells innovative systems for air quality monitoring and industrial gas analysis. The product portfolio is organized around two main divisions: products for air quality monitoring (ambient air quality) and products for emissions monitoring and process control. Core technologies include DOAS (Differential Optical Absorption Spectroscopy) products using xenon lamp light sources with spectrometers or interferometers, Laser Diode Systems (TDL technology) including the LD500 analyzer for industrial applications, and Particulate Monitors using beta absorption, triboelectric, and optical methods. The company also offers turnkey solutions, data loggers, and supplementary products. Specialized products include the DX100 for dioxin and CO2 sampling, System 400 with multiple configurations (cross-stack, fast-loop, HWE), Real Driving Emissions monitors, and Oxygen monitors using zirconium dioxide technology. Marine-specific solutions include the M800 system. Opsis also operates two sub-brands: LiquidLINE and Liquid Monitoring for laboratory liquid analysis instruments.

Broad incumbents

• Endress+Hauser: Endress+Hauser is a global process instrumentation leader that offers gas analysis alongside flow, level, and analytical instrumentation; it overlaps with OPSIS in industrial gas and emissions analytics but serves a much broader process instrumentation portfolio.
• Thermo Fisher Scientific (Process Analytical): Thermo Fisher's Analytical Instruments segment includes process gas analyzers, FTIR, and ambient air monitoring instruments that compete with OPSIS's offerings across industrial emissions and ambient air markets, though as part of a much larger scientific instrument portfolio.
• Siemens Energy (CEMS / process analytics): Siemens Energy offers CEMS, continuous gas analysis, and digital emissions solutions that overlap with OPSIS in power generation and heavy industry, while competing against the broader analytical and emissions stack.

Direct peers

• DURAG Group: DURAG is a German specialist in combustion and emissions monitoring for power plants, cement, waste incineration, and process industries — competing head-to-head with OPSIS in CEMS, particulate measurement, and flue gas analysis.
• HORIBA: HORIBA's process and environmental division supplies stack gas analyzers, automotive emissions test systems, and ambient air quality monitors, competing with OPSIS in CEMS and ambient air monitoring for both industrial and regulatory customers.
• Focused Photonics (FPI): FPI is one of the largest Chinese suppliers of CEMS and process analytical instruments, often competing on price in cement, steel, and power plant emissions monitoring — comparable to OPSIS's emissions monitoring solutions in the same verticals, especially in Asia.
• AMETEK Process & Analytical Instruments: AMETEK's Process & Analytical Instruments division offers FTIR, NDIR/UV, and laser-based gas analyzers for industrial emissions and process monitoring — directly comparable to OPSIS's DOAS, FTIR-DOAS, and TDL product range serving similar end markets.
• SICK AG: SICK is a German manufacturer of industrial gas analyzers and process instrumentation with a comparable product line in CEMS, emissions monitoring, and ambient air quality — directly overlapping OPSIS's DOAS, FTIR, and in-situ gas analysis portfolio in industrial and environmental applications.

Emerging players

• Aeroqual: Aeroqual specializes in compact sensor-based air quality monitoring stations for ambient and indoor applications — overlapping OPSIS in urban and industrial air quality monitoring, but with a lower-cost, lower-spec sensor approach rather than DOAS spectroscopy.
• 2B Technologies: 2B Technologies makes portable and stationary instruments for ozone, NO2, mercury, and other gases for ambient and emissions monitoring — comparable to OPSIS at the lower-end and benchtop portion of the analytical instrument market.
