Ensure accurate particulate emissions monitoring with the ENVEA QAL 181 – a QAL1-certified forward scatter particulate CEM designed for low dust concentrations in dry industrial processes. Built with robust ProScatter™ technology, it delivers precise measurement with reduced sensitivity to particle type and size, while withstanding stack temperatures up to 500°C. Ideal for incineration, cement, power, metals and chemical applications, the QAL 181 helps operators maintain compliance, improve reporting confidence, and monitor emissions reliably in challenging environments.
