PM2.5 and PM10 particulate matter concentration meter

The DT-968 meter is an ergonomic device for measuring the concentration of PM2.5 (i.e. atmospheric aerosols with particle size of 2.5μm or less) and PM10 (all particles of 10μm and smaller) in the air, as well as for measuring climatic data (temperature and humidity). The DT-968 meter's sensor for measuring PM2.5 and PM10 is a laser system that uses a light scattering method to detect and count particles in the concentration range from 0 µg/m3 to 2000 µg/m3. The air sample is sucked into the instrument through a grille on the front panel using a built-in pump, and then enters the measurement chamber. In this chamber, a laser light source illuminates the particles and as the air sample passes through the laser beam, the light source is obscured which is recorded by the light detector. The signal thus generated is converted into an electrical signal and analyzed to calculate the concentration in real time. The lightweight design and small dimensions allow one-handed operation. The meter is straightforwardly ideal for measurements in small spaces.
