Introduction:
Research show that: longtime exposure to particulate matter especially the particulate matter smaller than 2.5 micrometers ( PM2.5 ) which can go directly to the alveoli of the lungs, is a major health hazard.
This particulate matter cannot see by eyes, handheld particle counter is a device to detecting particulate matter content. Main accessories: laser device, sensor, air sampling unit and electronic control system.
At the same time of continuous monitoring dust concentration, handheld particle counter also collecting particulate matters and doing analysis, then offer air quality weight, there is a formula calculate quantity at the same time, so device show both particles weight and quantity at the same time.
Using this device we can know the difference before and after using air purifier
