Product Name：DMH-635 Handheld Laser Dust Monitor

     The DMH-635 Handheld Laser Dust Monitor uses the principle of light scattering to detect the concentration of suspended particles in the air. It can use three channels (PM 1.0, PM 2.5, PM 10.0) simultaneously to measure and display the results,  and has the characteristics of fast detection speed, light weight, small size, and easy operation. The DMH-635 Handheld Laser Dust Monitor is computer controlled, it can both store and print sampled results as well.
