This handheld PM2.5 detector is a
special detection instrument for measuring PM2.5 (particulate
matter that can enter the lung) and PM10 (particulate matter that
can be inhaled) in the air. It is based on the international advanced
high sensitivity micro laser sensor technology development, and it
is a high-tech product integrating aerodynamics, digital signal
processing and opto-mechatronics. The instrument has the
characteristics of high precision, stable performance, strong
functionality, simple operation and large capacity data storage. CW-HAT200 （ S ） handheld PM2.5 detector can be widely
applied to the determination of public environment and
atmospheric environment, and also used for the evaluation and
analysis of the purification efficiency of air purifiers. It has up to
500 sets of measurement data storage, which can be high-speed
download through USB interface.
