Handheld particle counter (PM2.5 detector )
Product introduction:
PM2.5 air quality detector is dedicated to measure the air PM2.5 (which can go directly to the alveoli) numerical dedicated testing instrument. Applies to public places and the atmospheric environment , can also be used for air purifier, purification efficiency evaluation analysis.
Working principle:
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.
The main parts of handheld particle counter:
1.A laser device: Light intensity, distinguish ability to distinguish 0.3 particles, so can more accurately detect particulate matter.
2.Sensing device: High quality turbofan working time over 30,000 hours with stable running speed. To preach the sample gas sensor with a stable.,can make the sensor data is more stable. Low noise, suitable for household environment.
3.Suction gas sampling device: A short time sampling, just need 35 seconds.
4.Electric control part.
