What is QAL2, and how does Etalonair get involved ?

QAL2 (Quality Assurance Level 2) is a mandatory normative procedure (EN 14181) for continuous automated measuring systems (AMS) monitoring atmospheric emissions. It involves calibrating the AMS instrument in the field by comparison with a reference method. Etalonair supports its clients in setting up, carrying out, and monitoring QAL2, using its certified technicians and reference equipment.
