Handheld Dust Meter LDMH-A10 is air quality analyzer used to monitor the concentration of particles in the air. Adopted with light scattering principle with fast detection speed. The dust meter is small, lightweight, making it handheld device. It simultaneously measure and display the results for three channels (PM 1.0, PM 2.5, and PM 10.0)
