- The PCME QAL 181 is an approved Particulate Continuous Emission Monitor (CEM) providing high quality emission measurement for low dust concentrations from industrial processes, especially in Incineration, Power Plant and Cement Kiln applications. The instrument provides a proven solution for applications where CEN standards EN 14181 / EN 13284-2 are applied (plant falling under the Waste Incineration and Large Combustion Plant EU Directives). The instrument holds QAL1 approval as specified in EN 15267-3, under both MCERTS and TUV, in addition to compliance with US EPA standard PS-11 for PM-CEMs.
- PCME's patented ProScatter™ Forward Scatter technique measures the light from a laser source scattered by particles in a near-forward direction and results in an improved signal to noise ratio compared to other techniques, with excellent resolution and zero drift characteristics. This allows for high stability even at low concentrations (< 0.1 mg/m3) as well as rugged operation in stacks where emissions exceed 100 mg/m3.
- Reliable and rugged design, proven for long term operation at elevated temperatures and with minimised instrument maintenance
- System self-checks, with logging of Zero and Span check data for QAL3 reporting
- QAL Reporter PC software option to provide secure and powerful emissions reporting and automated QAL3 reporting in full compliance with EN 13284-2
- Entry and Standard control units with advanced graphics and user interface screens, features including alarming, graphical trending, data logging, 4-20mA output
- PLUS control unit option for sensor networking (up to 16 sensor channels) via industry standard Modbus, multiple inputs for external devices (e.g. for Temp and O2 normalisation)
