CPA1, Flue Gas Analysers, covers what you’ll need to know in order to use a flue gas analyser.  

CPA1 training is normally completed within half a day, plus additional time to sit the theory & practical assessments. Please also note that since April 2012 CPA1, Flue gas analysers, are also a mandatory requirement. If you currently hold CCN1 and are not planning to retake you should complete CPA1 as an isolated assessment. If you are retaking your CCN1 or taking it for the first time it will be included within the CCN1 core assessment.
