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)
