LaserDust is a laser-based dust monitor that measures dust concentration in stacks and ducts on the duct, with a transmitter and receiver positioned on either side. It measures low dust loads in scattering mode and high dust loads in transmission mode. There are three models by optical path length: MP (0.5 – 3 m), LP (3 – 6 m) and XLP (6 – 10 m).

The instrument operates above the dew point at process temperatures up to 700 °C. It is used for bag filter and electrostatic precipitator fault detection, emission monitoring and process control. An ATEX dust monitor version and a high-temperature option are available.
