Particulate CEM for wet gas streams

QAL1 approved ProScatter™ particulate CEM for the extractive sampling and measurement of particulate in saturated wet gas streams.

Continuous Particulate Monitoring for saturated wet stack applications typically found after wet scrubbers, wet electrostatic precipitators and wet flue gas desulphurisation plant.

QAL1 certified against EN 15267-3 to meet EN 14181 and other International standards

FEATURES AND BENEFITS

Extractive sampling system configurable for fixed velocity or isokinetic variable flow rate sampling
Continuous Particulate Monitoring for saturated wet stack applications typically found after wet FGDs or filtration systems that produce a wet/condensing flue gas (wet ESPs/scrubbers)
Meets QAL1 and other International standards
Heated sample lines to maintain sample temperature and prevent the formation of condensation
Forward Scatter measurement technique with automatic zero and span (upscale) checks
Easy to use intuitive multi-lingual menu with large display for improved user interface complete with on-board diagnostics and multiple analogue and digital communication outputs
Small sample chamber and use of advanced polymers – prevents particulate adhesion, condensation and crystal formation. Reduced maintenance for the end user
