It can also measure the mass concentration of the particles PM10 and PM2.5 during the measurement of particle size distribution

DS-1116 Aerosol Spectrometer

The working principle for DS-1116 is that a laser light source irradiates on the particles; then the solid state detector detects the scattered light; and at last, the optical signals are turned into electrical signals. The electrical signals are classified and counted according to the pulse amplitude after amplification, and then been accumulated in the register. After that the number of the particles could be calculated out after a period of time, and thereby the concentration of the particle will be calculated out.

Characters:

l        DS-1116 aerosol spectrometer can also measure the mass concentration of the particles PM10, and PM2.5 during the measurement of particle size distribution (particle size ranging from 0.3-25um, 16 particle size channel).

l       The instrument is widely used in a variety of indoor and outdoor environmental pollution test.
