Welcome to TCQA Labs, your trusted partner in environmental compliance. We are proud to be India's first and only laboratory offering specialized testing services for QAL3 of Continuous Emission Monitoring Systems (CEMS). Our unique expertise and indigenously developed state-of-the-art facilities ensure that your emissions monitoring equipment meets the highest national and international standards.
QAL3 (Quality Assurance Level 3) is a crucial periodic functional test performed by the plant operator. It is a routine quality control check to demonstrate that the CEMS's performance remains within the required limits over time, ensuring continued correct operation in its real-world environment. A QAL3 test primarily involves zero and span checks to verify that the CEMS is not drifting. Without regular QAL3 checks, the integrity of your emissions data cannot be guaranteed.
The Central Pollution Control Board (CPCB) in India mandates the regular, ongoing quality control of CEMS. Our services for establishing and maintaining QAL3 procedures align directly with these CPCB guidelines, providing your facility with verified, credible, and legally defensible data for continuous compliance.
This European standard provides the framework for the quality assurance of CEMS, defining the three core levels (QAL1, QAL2, QAL3) and the mandatory Annual Surveillance Test (AST). Our QAL3 procedures are conducted in strict accordance with DIN EN 14181 to ensure your system performs correctly year after year.
The core of a QAL3 test is a regular verification of the CEMS's zero-point and span-point. By checking these two key reference points, we can monitor the system's drift and confirm that it remains within the manufacturer's specified performance limits, ensuring data accuracy.
We bring global standards like DIN EN 14181 to your doorstep. Our team of experts understands both international best practices and the specific requirements in the context of Indian tropical conditions, as well as Indian regulatory requirements.
We can provide the necessary on-site support and training to help your team properly execute routine QAL3 checks, ensuring your CEMS is performing accurately and reliably over time.
Our services provide independent, third-party assurance of your CEMS's continued accuracy and reliability, which is essential for building and maintaining trust and credibility with regulatory bodies like the CPCB over the long term.
By ensuring your CEMS is properly checked on a routine basis, we help you avoid potential fines, legal issues, and operational shutdowns that can result from a CEMS that drifts out of calibration over time.
Quality is at the heart of everything we do.
ISO/IEC 17025 Accreditation: We are an ISO/IEC 17025 accredited testing laboratory by the International Accreditation Service (IAS, USA), an ILAC member, a globally recognized body. This is the standard for labs worldwide, proving our technical competence and ability to produce precise and accurate data. It also validates our technical capabilities and the international acceptance of our test reports.
