The analysers use infrared spectroscopy to determine the pollutant levels as the gases diffuse into the stainless steel measurement chamber. It provides a high accuracy, low maintenance measurement of the combustion process. It is capable of operating in very high dust loading conditions, up to several gm/m3 of dust. Its performance can be verified automatically or manually on demand by the injection of zero and span protocol gases into the probe measurement chamber.
Available with either single species measurement for process control or with multi-species measurements for a choice of emission monitoring.
