DMH-635 Handheld Laser Dust Analyzer Introduction: The DMH-635 handheld laser dust analyzer is used to monitor the concentration of suspended particles in the air. It adopts the principle of light scattering, has 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. Application environment: 1. Applicable to the determination of dust concentration in production sites of labor departments in industrial and mining enterprises 2. Monitoring of inhalable particulate matter in public places of health and epidemic prevention stations 3. Environmental protection monitoring department conducts atmospheric dust detection and pollutant investigation 4. On site testing of scientific research, filter performance testing, and other aspects 5. On site dust concentration measurement and exhaust dust concentration monitoring 6. Indoor air quality testing 7. Various scientific research institutions, meteorology, public health, air pollution research, etc characteristic: 1. switchable counting accumulation mode, counting mode can simultaneously detect six channels: 0.3um, 0.5um, 1.0um, 2.5um, 5.0um, 10.0um 2.
