What is QAL1 Certification?
QAL1 is a performance certification standard defined under the European standard EN 15267. It verifies that a Continuous Emissions Monitoring System, meets strict requirements for accuracy, stability and long-term measurement reliability. To achieve QAL1 certification, an analyser must undergo independent laboratory and field testing to demonstrate that it can consistently deliver high-quality emissions data under real operating conditions.
In simple terms, QAL1 confirms that the technology has been rigorously assessed and approved as suitable for regulatory compliance monitoring. It gives operators confidence that the analyser will perform as expected, even in demanding industrial environments.
Why QAL1 Matters for Emissions Monitoring
For any site operating under environmental permits, the accuracy and reliability of emissions data is essential. QAL1 certification ensures that the monitoring system is capable of delivering measurements that meet the strict standards required by regulators. This helps operators report their emissions with confidence and avoid compliance issues or penalties caused by inaccurate readings.
QAL1-approved systems also provide strong long-term value. Because they are tested for stability and repeatability, operators can rely on consistent performance with fewer interventions, fewer false alarms and reduced downtime. This supports smoother plant operations and helps maintain compliance without unnecessary maintenance overhead.
CODEL’s Use of QAL1 Certification
CODEL has relied on QAL1 certification for many years as a benchmark for proving the accuracy and reliability of our emissions monitoring systems. This commitment is reflected across our extensive certified product portfolio, which includes the GCEM 40 Series, DCEM2100, VCEM5100 and DCEM 6000. Each of these systems has undergone rigorous, independent testing to meet the demanding performance requirements set out under EN 15267.
We continue to build on this foundation with the upcoming GCEM 50E, which will also carry QAL1 approval. By ensuring our analysers meet these recognised standards, we provide operators with confidence that their monitoring equipment is compliant, robust and capable of delivering high-quality data in challenging industrial environments.
Why CODEL Uses QAL1-Certified Technology
CODEL products are engineered to meet the highest industry standards, with systems such as the GCEM 40 Series certified to QAL1 under EN 15267. This demonstrates our commitment to providing emissions monitoring solutions that offer proven accuracy, reliable performance and long-term stability.
For operators, choosing a QAL1-certified CODEL analyser means choosing a system that has been independently validated to meet demanding environmental and regulatory expectations while also offering the practical benefits of stable, low-maintenance operation.
