Measuring Particulate Matter 

Very helpful and clear video. Seems like indoor air, and noise, are often overlooked or underappreciated when it comes to impacts on human health. Keep up the good work!

Very good Vedio, as I am doing research in these topics.

How can I measure the amount of particulate matter in the exhaust of a vehicle?

Hi I live in India. where exactly can I purchase these devices to measure particulate matter? Is there a device to analyse the particulate matter is as well? Thanks you so much for your knowledge. I really appreciate the video
