PS11 Capable Forward Scatter Particulate CEM
STACK 181
US EPA PS11 compliant ProScatter™ particulate CEM providing high quality emission measurement for low dust concentrations from industrial processes
Utilising the patented ProScatter™ Forward Scatter measurement technique for measuring particulate concentration levels, typically between 0.06 mg/m3 to 300 mg/m3, this measurement technique offers improved levels of performance which make the STACK 181 very suitable for use as a PM CPMS or PM CEMS that need to comply with US EPA PS-11 for Site Operators looking to satisfy the recent MACT and MATS rules.
The STACK 181 is suitable for measuring particle emissions after both bag filter and electrostatic precipitator arrestment plant.

- 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
- For use as PM-CPMS or PM-CEMS that need to comply with PS-11
- ProScatter™ technology offers enhanced measurement due to reduced cross-sensitivity of particle type and size
- Features automatic zero and upscale checks that fully challenge the system’s ability to measure forward-scattered light and satisfy daily drift checks
- Easily audited with manual filters
- Stacks after bag filters, cartridge filters, cyclones, electrostatic precipitators, no filtration.
