We carry out technical checks, adjustments and calibrations with calibration gas. We do not carry out accredited measurements such as QAL2 and the annual surveillance test (AST), nor accredited calibration. As the operator, you remain responsible for QAL3. We perform the checks, manage the records and deliver trend and status reports.
QAL3 is the ongoing quality assurance during operation: regular checks of zero and span that are followed over time, so that drift is detected in good time. QAL2 and the annual surveillance test (AST) are parallel measurements carried out mainly by an accredited laboratory. All three are part of EN 14181. For measuring systems under the Swedish NOx charge, the checks are adapted to the applicable requirements.
