Many important industrial gases absorb infrared light at their own characteristic wavelengths, and infrared analysers use this to measure them. Because each gas absorbs differently, infrared technology gives fast, selective, and stable readings without consuming the sample. It is one of the most widely trusted methods for measuring gases such as CO, CO2, NO, SO2, and methane, and it forms the basis of many emissions and process monitoring systems. The right infrared analyser depends on the gases you need to measure, the concentration range, and the conditions of your sample. TC Limited manufactures infrared analysers for process control, safety, and emissions monitoring, and every analyser is supplied complete with a sampling system matched to your application.
