Fine particulate matter dust tester laser particle counter

Knowledge of the Fine particulate matters
Fine particulate matters under 100 micron called total suspended particles in the air (TSP)
Fine particulate matters above 10 micron called can be inhaled particulate matter(PM10)
Fine particulate matter under 2.5 micron can go into the lungs (PM2.5)

Working Principle of Handheld Particle Counter
Using the latest sensor technology and efficient microprocessors, to outdoor or interior air quality test at any time.
The laser after dust particle scattering, the optical sensor output pulse signal to digital signal processing, measuring parameters, the results show, buttons, time, date etc are controlled by a built-in microcomputer (MCU) and implementation.

Laser Particle Counter Introduction
Laser Handheld Particle counter is the best machine to check fine particulate counter in the air.The best helper to demo the features and capabilities for air purifier.35 seconds to get the blew test result.
1). The quantity of fine particulate mattes : 0.3μm, 2.5μm
2). The weight of fine particulate mattes: 2.5μg/m³, 10μg/m³
3). Test temperature and humidity in the same time.
4). Purification rate between 2 times test result.
5). 6 records for the testing result. Easy make a comparison.
