The GCEM40 series is the latest generation of CODEL's world renowned in-situ monitors. Our development, knowledge and practical experience have been utilised to produce this advanced technology gas analyser which gives complete flexibility of use on process or emissions applications whilst delivering superb accuracy and repeatability at a very competitive price.

Designed for use primarily on combustion processes, the GCEM40 series measures key pollutants such as CO, NO, NO2, NOx, SO2, CH4, CO2 and H2O using an infra-red spectroscopy to ensure that there is no cross sensitivity from other contaminants in the gas stream.
