PM2.5 Dust sensor

 

PM2B/PM2D series of products is a laser - type dust sensor.The amount of light dispersion and pulse intensity generated by the laser light source through the sampling gas can accurately measure the number of PM2.5 particles distributed in the air per unit volume, and calibrate the mass concentration of output particles through mathematical algorithm and science.

 

PM2B/PM2D sensor has the characteristics of high sensitivity, fast response, long service life, beautiful appearance, and easy installation and use.It is a professional PM2.5 measuring equipment.It is suitable for air purification system, fresh air system and widely used in modern buildings, intelligent air conditioners,equipment cabinets,

machine stations, subways, airports, schools and other places.
