Model 600 SC FTIR - Fourier Transform Infrared Analyzer



The California Analytical Instruments 600 SO FIR Analyzer provides fast; continuous and stable analysis of virtually any gas that has an infrared absorption spectrum. The proprietary sample cell enables the instrument to accommodate hot samples containing high levels of moisture. The 600 SC FTIR can serve a variety of analytical applications, including diesel emissions, OEM monitoring, ammonia slip, SCR inlet/outlet monitoring, process monitoring and others. Unlike other FIR analyzers, the 600 SO FIR does not require liquid nitrogen, eliminating the need to constantly fill LN2 dewars and the associated safety issues. Its small footprint and lightweight allow easy installation and transportability when required.
