4650-PM (Compliance Dust)

High-sensitivity, forward-scatter laser measurement for particulate matter, for use in combustion processes where condensed water is not present (for sale in the USA and China only). 4650-PM provides the stable, accurate low-range measurement of particulate matter in stacks and ducts where water droplets are not present in the flue gas. NOTE: The 4650-PM is currently available only in the USA and China. Consisting of a stack-mounted probe and separate control unit, 4650-PM's forward scattering laser measurement detects particulate matter at low concentrations. This enables closer emissions control, with a more accurate measurement than similar PM monitoring systems. Maximum measurement stability is achieved through an advanced optical system with a lower angle of incidence than competing systems, resulting in a lower detection limit, while the optics are fixed for measurement reliability. Ideally suited for use in combustion processes located after the baghouse or electrostatic precipitator, 4650-PM is ideally suited for use in the power generation, glass, industrial boilers, speciality metals and pulp & paper industries.
