MAS Dust

MAS 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.

MCERTS certified-accurate particulate matter monitoring data

Continuous and simultaneous measurements of PM₁, PM₂.₅ (FSP), PM₁₀ (RSP), and TSP.

Environmental Monitoring and Audit (EM&A) compliance for construction dust monitoring and Transfer Standard (TS) applications

Product Detail

MCERTS Certified, Fully Compliant, Monitor All Particulates – PM₁ to TSP

The system ensures reliable particulate monitoring through three key innovations: 1) an intelligent heated inlet with adjustable humidity thresholds to prevent condensation; 2) autozero calibration eliminating photometer drift; 3) sheath flow stabilization for consistent long-term particle counting.

Certification

As an ISO 9001 and ISO 14001 certified company, we are committed to technological excellence and sustainability.

Effectiveness in Evaluating Roadside Air Quality for Milan Government

Sector：Traffic and Marine Emission

Location：Milan, Italy

The traffic emissions are generally monitored by the traditional fixed reference stations. However, those stations are not only expensive to operate, but also unable to monitor emission sources at a close range. This limited their effectiveness in studying local pollution problems. To better understand the traffic emissions in Milan, Italy, the city's environmental agency AMAT (Agenzia Mobilità Ambiente e Territorio) deployed three Sapiens MAS-AF300 in the city to evaluate the advanced air quality sensors compact station’s capability to detect exposure to vehicular traffic-related emission
