- The CEM500 is an extractive online gas analysers dedicated to continuous emission monitoring using a very high resolution spectrograph (0.1 nm) with an ultra sensitive 2048 pixels CCD.
- It covers applications like DeNOx systems on power plants, generators, chemical plants, petro-chemical plants, or biogas reactors.

- It covers applications like DeNOx systems on power plants, generators, chemical plants, petro-chemical plants, or biogas reactors.
- The CEM500 is based on UV spectroscopy that brings a higher sensitivity and stability than infra-red systems and also gives the possibility to measure several gases simultaneously, example: NH3, SO2, NO.
- 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, CS2 and others.
- All the internal gas circuit is heated at 190°C to admit directly hot and humid combustion gas.
- There no risk of interference with H2O, CO, CO2 or CH4 as all theses gases have no absorbance on the UV range.
