Pocket laser respirable dust continuous tester / dust continuous tester

The Pocket Laser Respirable Dust Continuous Tester is used to measure the concentration of respirable dust (PM10/PM2.5) in the air of public places. It can also be used for the amount of dust particles with a particle size of 0.5 and 5.0 μm per unit volume of air in a clean environment. It is a new generation of intelligent measuring instruments that are quickly measured in real time by the Centers for Disease Control and Prevention, Health Supervision, and Environmental Monitoring. The instrument adopts the advanced light scattering principle to use the semiconductor laser as the measuring light source to perform highly sensitive non-contact measurement of dust in the air. It is managed and controlled by a single-chip microprocessor. It uses a high-resolution large-screen high-brightness liquid crystal display and is displayed in Chinese.
