Tethys Gas Analyser - EXM500

The EXM 500 is an extractive on-line gas analyser dedicated to continuous emission monitoring (CEM). 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 periodicstructure 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.

There no risk of interference with H2O, CO, CO2 or CH4 as all theses gases have no absorbance on the UV range.
