PM-900 is a laser-based particle sensor which uses light scattering method to detect and count particles and calculate PM1.0, PM2.5 and PM10 concentration in a given environment. The sensor features an imported processing chip and photosensitive element. Signals are collected and processed by the microprocessor chip and then output in digital format. The sensor is ideal to detect the concentration of different particles precisely in real time.
1. Adopted by new-advanced fourth generation laser particle sensor, based on Mie-scattering theory, it can accurately measure PM1.0/PM2.5/PM10, other particles as small as 0.3um, making particle measurement more accurate.
2. High-performance laser module, depth algorithm optimization compensation, airflow constant system, making measurement more accurate and stable.
3. It has a long life time up to 20,000 hour accompanied with Industrial-grade components.

The sensor is based on the particle concentration analysis technology of Mie scattering theory. A laser light source illuminates a particle as it is pulled through the detection chamber. The particles are scattering when passing through the laser beam. The information processing circuit converts the light intensiElitechustorety signal of the scattered light via the photoelectric sensor into a voltage pulse signal, which is preamplified, converted by AD into digital signal. After noise processing and optimal algorithm analysis, particle count with the equivalent particle size per unit volume can be obtained, and then the particle concentration is calculated.
