(*) Light scattering technologies applied to particle mass concentration measure can be affected by aerosols chemical composition and atmospheric conditions & should be subject to operator interpretation.
The MP101M, based on the beta attenuation measurement technique, determines the particles concentration by measuring the amount of radiation that a sample, collected on a fiber tape, absorbs when exposed to a radioactive source.
Low energy beta rays are absorbed by collision of dust, whose number is proportional to density. Absorption is thus a function of the mass of the irradiated material, independently of its physico-chemical nature.
The OPM’s (Optical Particulate Monitor) principle is based on the measurement of the light scattered by the particles. A powerful algorithm is applied to continuously convert the signal into mass concentration.
Combination of both technologies provides simultaneously approved particulate measurement PLUS real-time indication of PM10, PM2.5 and PM1.
