What quality control measure does an emission analyzer perform?

An emissions analyzer incorporates self-tests as a critical quality control measure to ensure its accuracy and reliability. These self-tests are designed to evaluate the performance of the analyzer continuously or at specified intervals, checking various parameters like sensor response, signal accuracy, and internal software functionality. By conducting these automated assessments, the analyzer can identify potential faults or deviations from expected performance levels, enabling prompt corrective actions. This means that the analyzer can maintain consistent operational standards and provide accurate emissions data, which is essential for compliance with environmental regulations and for achieving quality assurance in emissions testing.
