The 31121 is a thermoelectrically cooled (TEC) laser module used to measure nitrous oxide (N2O) and carbon dioxide (CO2). It is used in the TGA200A or in prior TGA models that have been upgraded to use a TEC laser. Contact Campbell Scientific if you are interested in upgrading an older TGA analyzer with a new TEC laser. For performance specifications, see the TGA200A.
