Product descriptionMAS Dust is engineered for high-performance, long-term outdoor particulate matter monitoring, featuring integrated autonomous data quality control. Equipped with an advanced particle counter based on light scattering technology (optical approach), it simultaneously measures mass concentrations of PM₁, PM₂.₅ (FSP), PM₁₀ (RSP), and TSP. We are proud to announce a significant industry milestone: our MCERTS-certified MAS-Dust monitors have been selected as the technology of choice for the very first projects operating under Hong Kong's newly implemented Environmental Monitoring and Audit (EM&amp;A) Manual. These pioneering projects—the San Tin / Lok Ma Chau Development Node and the Northern Link—represent the future of large-scale, government-mandated infrastructure and require the highest level of environmental data integrity. Why MAS-Dust is the Ideal Solution for the New EM&amp;A Framework? The MAS-Dust system is specifically designed for the rigors of major construction projects. Its core technology utilizes an active intake and a pump-based fixed flow system, ensuring consistent, representative air sampling that is critical for high-precision monitoring. Furthermore, it features an integrated heating tube to prevent moisture buildup in Hong Kong's humid climate, effectively eliminating abnormal conditions and avoiding false non-compliance reports. This robust design guarantees that the data you receive is not only compliant but truly reliable.Please contact us for price details
