Gas analyzer 7000 FTIR

monitoringautomotivespectrum

Overview The ENVEA 7000 FTIR analyzer provides fast, continuous and stable analysis of virtually any gas with an infrared absorption spectrum. The 7000 FTIR uses Fourier transform infrared spectroscopy and PLS chemometrics to measure multiple gas components simultaneously through a rugged interferometer and a 10.2 m multi-reflection heated sample cell, delivering accurate concentration results.
