PM2510T dust detector is a detection instrument for measuring the mass concentration of dust in unit volume of air in the environment. This instrument adopts the principle of light flash and uses international new sensors to detect the mass concentration of dust in the air. It is a high-tech product integrating optics and laser technology, electronic technology, computer technology, precision machinery, aerodynamics, and other disciplines. It has the characteristics of high measurement accuracy, reasonable detection, stable perfor-mance, multiple functions, unique modelingsmall size, light weight, and convenient detection and carrying. This instrument is designed to detect particle size grades and sampling methods in accordance with international standards, and its performance indicators comply with national standards and national metrological verification regulations. It is widely used in environmental air quality, atmospheric analysis,aerospace and other depart-ments
