The PCME QAL 360 sensor series is suitable for measuring dust concentrations in Incineration, Combustion and other industrial stacks and is compliant with EN  15267 meeting the QAL1 requirements of EN  14181. Having a 0–7.5 mg/ m³ certification range, the PCME QAL 360 can be used at low or high dust levels, meeting the tightened minimum emission limit value of 5 mg/m³ for Large Combustion Plant specified in the Industrial Emissions Directive. Due to dynamic ranging the sensor is also suitable for much higher dust levels found in Power, Cement and Metals smelting processes.
