QAL1 Approved Back Scatter Particulate CEMS

QAL 360

TÜV QAL1 and MCERTS Approved, Stand alone or networked system option Particulate CEM providing high quality emission measurement for dust concentrations from industrial processes

Having a 0–7.5 mg/m3 certification range, the QAL 360 sensor can be used at low or high dust levels meeting the tightened minimum emission limit value of 5 mg/m3 for Large Combustion Plant specified in the Industrial Emissions Directive.

Certified to 7.5 mg/m3

  • ProScatter™ Backscatter sensor technology with superior minimum detection <1 mg/m3
  • Certified to 7.5 mg/m3
  • Zero and Span (reference) checks available to ensure optimal instrument performance and compliant with QAL1
  • Automatic Contamination Check – fully interrogates the optical system
  • Purge Flow Fail Sensor option with inbuilt automatic optical shield activation
  • Flue Gas Blocker to protect Plant Engineers from harmful flue gases during maintenance
  • Stacks 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 / Coating Powder)
  • Power Generation Plant (eg Coal/Biomass)
