Opacity QAL1 Approved Particulate CEM STACK 710
QAL1 approved particulate CEM which meets US EPA PS-1 requirements for Opacity monitoring from combustion stacks
Robust multi corner cube reflector provides truer reflection of transmitted light compared to traditional “mirror type” reflectors providing greater confidence in measurement
Features & Benefits
- Outstanding reliability with no continuously moving parts
- Automatic in-situ zero and span checking with built-in calibration audit and zero drift correction
- Dual light source, with patented Flood LED source provides robust check of the detectors
- and minimises effects of temperature instability
Main applications
- 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 Refinery / Rubber)
- Power Generation Plant (eg Coal/Biomass)
