Medidor de polvo por difracción directa QAL1

QAL 181

Medidor de polvo por difracción (ProScatter™) para un monitoreo preciso de emisiones de baja concentración de procesos industriales

Rango de medición certificado QAL1 0 – 7,5 mg/m3, el más bajo del mercado

  • QAL1 certification ranges: 0 – 7.5 mg/m3, 0 – 15 mg/m3, 0 – 100 mg/m3, 0 – 200 mg/m3
  • Robust design with no critical moving parts
  • Available for use in high-temperature stack conditions and Ex hazardous zones
  • Easy to fit multi-patterned flange
  • Adjustable monitoring depth to ensure sampling in the most representative part of the flow path
  • Enhanced measurement due to reduced cross sensitivity to particle type and size
  • ProScatter™ technology offers enhanced measurement due to reduced cross-sensitivity of particle type and size
  • Easily audited with manual filters
  • Stack Particulate monitoring after bag filters, cartridge filters, cyclones, electrostatic precipitators, no filtration
  • Non-condensing / dry flue gases
    Typical Applications:

  • Incineration
  • Metals (eg Steel/Aluminium)
  • Minerals (eg Cement/Gypsum)
  • Chemicals (eg TiO2 / Refinery)
  • Power Generation Plant (eg Coal/Biomass)
