Flue gas analysis and a flue gas analyser enable you to
measure the concentrations of the pollutants present and to
adjust your burners for optimal combustion.
n exhaust-gas analyzer, particularly for emissions testing
of motor-vehicle engines has a sampling tube into which a
mixture of exhaust gas and ambient air is fed through gas
lines. A gas feed pump is disposed downstream of the
sampling tube with a flowmeter inserted in the air line
feeding electrical signals to a computing unit. The unit
computes instantaneous standard total flow rate, allowing
for gas pressure and temperature
