QAL1 Forward Scatter Particulate CEM QAL 181
QAL1 Approved ProScatter™ particulate CEM providing high quality emission measurement of low dust concentrations from dry industrial processes
4 QAL1 certified ranges, including 0 – 7.5 mg/m3, the lowest achievable for any PM-CEM
Features & Benefits
- 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
Main applications
- 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)
