The GCEM4000 is a multi-channel flue gas analyser that uses Non-Dispersive Infrared Absorption (NDIR) technology. It provides high accuracy, low maintenance measurement of all the key combustion process emissions to atmosphere. It is capable of operating in very high dust loading conditions, up to several gm/m3 of dust.
Its performance can be verified automatically or manually on demand by the injection of zero and span protocol gases into the probe sample chamber.
