Construction dust

With both the Institute of Air Quality Management and the Mayor of London recently publishing guidance on assessing dust emissions from demolition and construction sites, the launch of the new, web-enabled monitor reflects growing awareness of the impact of construction dust on air quality.

ET’s director of sales and marketing Duncan Mounsor said: "Even when developers don’t have to consider dust as part of planning, it – along with other pollutants like noise, smoke and odour – is classed as a statutory nuisance. Forward-thinking, considerate construction companies want to mitigate against both the potential risk of abatement notices and public health concerns.”

Using time-proven laser forward-scatter technology and physical sharp-cut cyclones to accurately affect the PM cut-point rather than mathematically try to calculate it, the single-channel real-time particulate CDM1 monitor measures either PM10, PM2.5 or TSP depending on which inlet head is fitted.

The dual-channel CDM2 can measure PM10 (or PM2.5) and TSP simultaneously. The CDM also utilises a RH controlled "smart-heater” inlet which helps ensure that measurement problems associated with humidity, mists and fog are minimised – a problem often seen with nephelomoters – leading to far greater confidence with the measurement data.
