Opsis CEMS – setting the standard for reliable and cost-eff ective solutions for monitoring air pollutants.
Opsis AB can supply a solution for almost all of your Continuous Emissions Monitoring Systems (CEMS) / process emission needs. Opsis will supply complete systems based on cross-duct, light absorption technology so there are no complex probes to degrade and maintain, making it ideal for stack monitoring applications, but especially so in applications with aggressive stack gas matrices. If required, Opsis can also supply more traditional, extractive-based CEM systems, though the analytical component is still based on light absorption. Additionally, Opsis provides supplementary sensors for a range of peripheral parameters including temperature, pressure, gas fl ow, dust concentration, oxygen and more, thereby providing a comprehensive package of analyses suitable for nearly all industrial applications.
Enviro Technology Services have been designing, installing, and supporting high-quality CEM systems since 1983 with MCERTS approved Opsis Differential Optical Absorption Spectroscopy (DOAS) cross-duct technology at the heart of our all of our installations. DOAS is an optical, multi-gas measurement technology that quantifi es stack gas components directly. In a typical cross-duct installation, there is no contact with the stack gases as they pass by, making analysis extremely fast. It is a true non-contact, non-extractive measurement based on the differential optical absorption of gas molecules in the UV, visible and IR wavelengths. Gases measured include: NOx
, NO, NO2 sensors added, dust, oxygen and more.
A typical CEM/process control system consists of one or two DOAS analysers (UV + FTIR) for measurement of gas concentrations, with peripheral measurements for e.g. fl ue gas fl ow rates and dust concentrations being measured by add-on sensors, tailored to suit specifi c customer needs.
Opsis CEMS Highlights: • High quality and high reliability • Maximum customer value and benefi ts • Minimum operator maintenance requirements • Minimal operating costs • Low cost of long-term ownership • Wide range of signal handling options • Range of dataloggers and software products • Easy integration into existing process control systems • Providing both real-time data and information for emissions reporting • MCERTS approved
Opsis’ systems for continuous emissions monitoring set the standard for reliable and cost-effi cient solutions for your industrial monitoring needs. Opsis CEMS are exclusively available in the UK and Ireland from Enviro Technology Services. No matter what your continuous emissions monitoring need is, ET has the answer, contact us to start the discussion today.

A unique ‘fi ngerprint’ approach to industrial gas analysis
Tunable AS showcased its cutting-edge gas fi ngerprint recognition technology at this year’s Sensor + Test event in Germany. This unique approach to gas analysis involves more than just measuring a gas’ concentration; it can detect complex and unknown mixtures of gases and odours by the use of powerful algorithms to understand patterns and relationships within the data accumulated. This ground-breaking approach gives the operator unparalleled insights into the make-up of the gases and odours analysed – resembling how our own sense of smell works. This technology is an exciting breakthrough for gas analysis applications such as air quality monitoring and process optimisation

In addition to the gas fi ngerprint recognition technology, Tunable displayed their gas analysis instrument, T2500 CEMS Analyser, which is ideal for the maritime industry as it detects and quantifi es all relevant greenhouse gases; it is insensitive to vibrations and has practically no operating expenses. This compact and stable process emission gas analyser operates with infrared (IR) absorption spectroscopy to provide precise analysis of CO, CO2 NO2
, SO2 and CH4 , NO, . It requires no consumables, such
as carrier or calibration gases – the sample gas is analysed directly as it fl ows through the analyser’s optical path. This robust instrument features an ultra-stable solid-state IR source which has proven its longevity with years of successful operation on offshore facilities – it requires no replacement for the lifetime of the instrument. Detaching the sample cell is easy and enables simple cleaning and maintenance – the instrument incorporates service indicators within the digital data stream to aid operators in planning maintenance schedules.
