Total suspended particles (TSP) is a regulatory measure of the mass concentration of particulate matter (PM) in the air. Particulate matter or particle pollution is a mixture of solid particles and liquid droplets present in the atmosphere. PM10 is particulate matter 10 micrometers or less in diameter, PM2.5 is particulate matter 2.5 micrometers or less in diameter. Exposure to these particles is harmful to health. When the level of these particles increases and penetrate deeply into the lungs, you can experience several health impacts like breathing problem, or burning sensation in the eyes. Due to small in size, both PM2.5 and PM10 particles act as a gas. When you breathe, these particles penetrate the lungs, which can lead to cough, asthma attacks, high blood pressure, heart attack and stroke. Serious diseases may also occur and as a result of which premature death can occur.
Qosain Dust sampler is a standalone device to sample PM2.5/PM10 particulate matter from the ambient air while logging the air volume, flow rate, humidity, temperature and several other quantities at run time. Qosain dust sampler includes a vacuum pump, logging circuitry and a WiFi terminal for standalone data acquisition on a smartphone or any WiFi enabled web browser. Note that internet is not necessary for data acquisition and system control. Dust Sampler is designed to work in various conditions. It can be used in open enviornment and even inside a building(with proper safety) where quality of air is critical.
