1、 Overview
The HJ-CW-HPC300 handheld laser dust analyzer is used to monitor the concentration of suspended particles in the air. It adopts the principle of light scattering, has a fast detection speed, is lightweight and compact, and is convenient for handheld operation. Using three channels (PM 1.0, PM 2.5, PM 10.0) to simultaneously measure and display results, this method complies with the Ministry of Health's WST206-2001 "Determination Method for Inhalable Particulate Matter (PM10) in Public Places - Light Scattering Method", JJF1190-2008 "Calibration Specification for Dust Particle Counter", and JJF1716-2018 "National Metrology Technical Specification".
This instrument adopts a semiconductor laser light source and a liquid crystal screen display. It has small size, light weight, high detection accuracy, simple and clear functional operation, computer control, and can store and print sampling results, making it very convenient to use.
