 The FGAII stack gas emissions analyzers use advanced dual sensor technology to measure the levels of up to 7 pollutant gases in a single compact unit.
FGAII gas analyzers carry a wide range of compliance and performance approvals including those from the US-EPA, UK MCERTS and German TÜV.
Our measurement technique ensures stable long-term operation with high accuracy and very low drift. Engineered for ease of maintenance and packaged for the industrial environment, FGAII stack gas emissions analyzers are simple to install and trouble-free in operation.

Advanced Dual Sensor Technology
The FGAII continuous emissions monitor uses Advanced Dual Sensor Technology (ADST) to measure specific pollutant gasses. This technique ensures stable long-term operation with high accuracy and ultra-low drift. FGA series emissions analyzers are simple to install and use, and trouble free in operation.
True NOx measurement
The FGAII is designed for very low level NOx measurement. The analyzer measures both NO and NO2 separately, these are combined to give a true NOx measurement output. The inherent problems with NO2 converters are therefore completely avoided.
NO Heated Sample Lines
Heated sample lines are not required in most applications. The sample gas is cooled and dried inside the ChillerProbe - advanced flue gas sample system.
