The EXM500 is an extractive online gas analyser dedicated to Continuous Emission Monitoring.
This new model is based on a 2048 pixels CCD (charge-coupled device) giving a higher resolution (0.1 nm) and a longer lamp life time (3 years) It is based on UV spectroscopy that brings a higher sensitivity than infra-red and gives the possibility to measure several gases simultaneously. A high selectivity is achieved by a fast Fourier transform (FFT) on the absorbance spectrum for all the gases having a periodic structure like NH3, SO2, NO and others.All the internal gas circuit is heated at 190°C to admit directly hot and humid combustion gases. The EXM500 is presented in a standard 19″ rack. This model may include a heated sampling pump as an option.
