? Real-time detection of dust concentration in the spraying area.

? The instrument uses the principle of light scattering to detect dust, and the detection is performed by a microprocessor.

? The data is calculated to directly display the dust mass concentration and converted into a data signal output. It uses a 320X240 color LCD with high brightness and full Chinese display. This instrument is small in size and easy to install. It has the advantages of fast detection speed, high sensitivity, good stability and simple operation. It can be widely used in various public places and electronic, optical, food and other fields.
