MP101M + OPM

Medidor MP101M com fonte Beta associado a sensor OPM (Optical Particle Monitor) opcional

O método de medição de fonte Beta ISO 10473 do analisador MP101M permite, quando utilizado com a tecnologia óptica do módulo OPM, a medição contínua e simultânea de partículas finas.
O instrumento de atenuação beta está em conformidade com EN 16450 para os padrões europeus PM10 e PM2.5. Certificado QAL1 pela TÜV, o MP101M também é aprovado como Método Equivalente Federal (FEM) pela EPA dos EUA para monitoramento contínuo de partículas finas em suspensão PM10 e PM2. 5

  • Monitoramento preciso de PM10, PM2.5, PM1

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.
