Overview

About MeFTIR Mobile Extractive FTIR

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.
