Simply speaking, it is measured based on the scattering of light by dust. The laser principle has two main uses. One is the detection of small concentrations of PM2.5, which is mainly used for environmental detection; the other is the detection of large concentrations of dust in the environment, which is mainly used to prevent dust explosions.
AGA6050 uses the principle of laser backscattering testing to complete the measurement of environmental dust concentration. The internal light source of AGA6050 emits a laser signal source that penetrates the environment and irradiates the dust in the environment. The irradiated dust will reflect the laser signal, and the reflected signal intensity changes positively with the dust concentration in the environment. AGA6050 detects the weak laser signal reflected by smoke and dust, and can calculate the concentration in the environment through a specific algorithm.
