Medida PM 2.5

Portable Particulate Monitor - Measure / PM10

The PM sensor head uses a laser and optical sensor to measure light scattered from particles passing through the laser beam. The optical sensor transforms scattered light into electrical signals which are processed to provide mass measurements – in this case PM and PM 10. Active sampling and humidity compensation

2019-04-29· How Is PM AQI Calculated? (Note: this is for the US AQI scale. We’ll be discussing different countries’ scales in the following section.) To calculate PM AQI, governments use a machine called a beta attenuation monitor that estimates the number of micrograms (the mass or weight) per cubic meter of air. (Here’s how they work.) So the raw number is the number of micrograms. Then ...
