Abstract
With the growing social progress, people's living environment gradually raise the level of attention to their own understanding of their environment and have increasingly high requirements, a single air sampling and dust samplers, and other products because of their performance and structural constraints And lead to gradually been eliminated by the community, people in urgent need of a compact, high performance, user-friendly comprehensive sampler. The design of the integrated flow of air sampler set of gas samples, dust samples and one is to facilitate the monitoring of professional staff, reduce its labor intensity of the development of a new generation of samplers. Advanced membrane flow sensors and microcomputer control combination. Flow of accurate, stable and flow of automatic tracking. Instantaneous, and the cumulative, standard traffic situation directly, readily available statistical sampling results. Power-down data protection, convenience store immediately to prevent data loss.
