Multi Component Exhaust Measurement System

The AVL SESAM i60 FT is an FTIR multi-component measurement system that measuresnumerous pre-calibrated gas components in a time-synchronous and dynamic manner.It can provide optimized analysis methods for different applications and fuels. Every singleFTIR comes with an individual gas calibration certificate and verified accuracy. The modularsystem allows for integration of optional conventional analyzers as well as a second FTIR.
