The DM 401 is a compact, in‑stack optical dust and opacity monitoring system designed for continuous particulate measurement in industrial stacks and ducts. It utilises a double‑pass transmissiometry method with a green LED light source to deliver high‑accuracy readings (±2 %), and features a robust, no‑moving‑parts design for minimal maintenance and long-term reliability. Ideal for applications across power plants, refineries, cement plants, baghouses, and more.
