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.
Â
Working principle:
The laser after dust particle scattering, the
optical sensor output pulse signal to digital signal processing,
measuring parameters, the results show, s, time, date etc are
controlled by a built-in microcomputer (MCU) and
implementation.
Â
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.
Â
2.Sensing device: High quality turbofan working time over *0,**0 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.
Â
3.Suction gas sampling device:
A short time
sampling, just need *5 seconds.
Â
4.Electric control part.
