Stack monitoring involves measuring gas concentration at the point of emission (stack).
These measurements can be coupled with ambient and background measurements to allow a better understanding of how emissions affect the local and broader environment. Stack emissions monitoring involves monitoring high concentrations of stack air such as CO, NOx, SO2 and others with specially designed gas analysers.
O2000 Oxygen Analyser
The O2000 ZrO2 Oxygen analyser is a versatile oxygen monitor for CEMS or process control applications. The O2000 Oxygen analyser has been tested and approved by a number of internationally recognized institutes and authorities, such as German TÜV and British MCERTS.
It meets the European directive, and is approved according to EN15267. Up to two probes can be used with one analyser.
The Opsis System 400 Continuous Emissions Monitoring System
The Opsis CEM system utilises proven non-contact, open path DOAS measurement technology in both the UV and IR range to provide an economic, fast, low maintenance, internationally approved multi-parameter continuous emission monitoring solution.
The Opsis System 400 is available in the following configurations as standard:
- 400BASIC: Basic system calibrated for SO2, NO and NO2.
- 400EXT: Extended system calibrated for SO2, NO,NO2, CO and H2O.
- 400WASTE: Extended system for waste to energy plants, calibrated for SO2, NO, NO2, CO, HCl & H2O.
Most importantly, an Opsis CEM system can be fully customised to exactly suit the client measurement requirements and can be installed as in-situ (System 400 CS), hot wet extractive (System 400 HWE), or fast-loop configuration (System 400 FL) integrated systems.
The brain of every Opsis CEM System 400 is at least one Opsis AR600 series analyser.
Opsis LD500 Series
The Opsis LD500 Analyser is the central unit in the laser diode gas monitoring system utilised in CEMS applications. It can house up to four laser diode heads. Each head is a complete laser control and data sampling system.
