The most common way to measure air quality as far as it concerns pm 10 and pm 2 5 particules is to use the so called beta attenuation monitors aka bam see picture on the right those are profesional equipment and also the only official equipment used for air quality monitoring in china us and most of the world.
Dylos air quality monitor readings.
For users of air quality monitors that display their readings only in particles per volume this necessity is problematic since no mathematical formula can quantify counts to mass.
Dc1100 features technology and engineering that allows monitoring of indoor air quality with an lcd screen that provides small and large particle counts with a dynamic bar graph showing actual count reading.
Air quality chart small count reading 0 5 micron 3000 very poor 1050 3000 poor 300 1050 fair 150 300 good 75 150 very good 0 75 excellent materials dylos dc1100 pro air quality monitor with pc interface 290.
Despite this obstacle it is still possible to estimate the mass of particulates using the dylos dc1100 pro monitor.
That unit displays two counts.

I bought the dylos pro.
The clean air healthy homes program cahhp at the university of montana s center for environmental health sciences created a spreadsheet and chart to convert dylos readings to µg m3.
Then i found out about the dylos air quality monitor.
Quoted from dylos s website it says that the dc1100 pro has all the features of the standard dc1100 but with increased lower sensitivity detecting particles down to 0 5 micron 0 5µ.
You can contact us at dylos corporation with your sales technical or general inquiries via the toll free number above our email address below or mailing address.
The large particle size range is calibrated to 2 5 microns 2 5µ and above.
Multiple modes including minute hour day and monitor to evaluate your air quality and store up to 30 days of air quality history for review.
Thank you for choosing dylos coporation your leader in indoor air quality monitoring.
The dc1700 pm is an improved version of the dc1700 battery operated air quality monitor.
This is essentially a relatively low cost consumer grade particle counter.
The dc1700 pm can display the particle readings as either particle concentration 0 5um 2 5um or as mass concentration in pm2 5 pm10 ug m3 for direct comparison to the epa.
The first count is for particles 0 5 to 2 5 microns in size per 0 01 cubic foot the second is for particles larger than 2 5 microns per 0 01 cubic foot.
I found out about this monitor by reading an article on woodgears ca.
The spreadsheet uses an algorithm to convert dylos particulate matter pm numbers from.
