MeFTIR

The MeFTIR (Mobile extractive Fourier Transform Infra-Red) instrument system is designed to measure gas concentrations of VOCs and other gases in the extracted air using internal IR-light.

The system’s Main Unit consists of an IR-spectrometer and a multi-pass Optical Reflection Cell mounted in a temperature-controlled enclosure. The system also includes vibration dampers, valves, hoses, air pump and mounting beams. IT-infrastructure including GPS-receiver, computer and monitor can also be provided on request.

Note: the MeFTIR system can be mounted on a mobile platform (vehicle) or in a stationary indoor space. A gas inlet for air extraction is needed.
Note: Local wind measurements are helpful for the data interpretation.
