Dust detectors are mainly used to detect the concentration of dust in the environment. Currently, people have increasingly high requirements for living, working, and living environments, and the sales volume of this instrument has also increased sharply. This industry is also being valued by more and more people.

　　Dust DetectorThe working principle of is mainly based on microcomputer laser principle and electrostatic induction principle.

Microcomputer laser principle:

When light shines on suspended particles in the air, scattered light is generated. Under certain conditions of particle properties, the scattered light intensity of particles is proportional to their mass concentration. Dust detectors measure the scattered light intensity and apply the mass concentration conversion coefficient K to obtain the mass concentration of particles.

Principle of electrostatic induction:

Utilize the dynamic charge induction between dust particles passing through the probe to generate a signal. The communication electrostatic technology determines the disturbance amount of the AC signal by monitoring the standard deviation of the charge signal, and determines the dust emission amount based on the magnitude of the instantaneous disturbance amount.
