GCEM40xx Gas Analyser - Extractive Mode
The GCEM 40xx gas analyser in extractive mode is field proven continuous emission monitoring system for difficult
applications. Designed exclusively for use on wide range of applications, where the flue gas temperature is abnormally
high, low or saturated.
Three decades of development, knowledge and practical experience have been utilized 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 competitive price.
The GCEM40 Extractive gas analyser is capable of measuring a range of CO, NOx, SO2, CH4, HCL, CO2, H2O and O2
simultaneously and with integral temperature and pressure sensors can compute fully normalized data directly in
mg/Nm³.
