Industrial-Grade Precision for High-Pollution Areas
Engineered with a high-performance laser sensor, the PMD371 delivers medical-grade accuracy even in most challenging air quality conditions. It monitors 7 particle size channels (0.3μm to 10μm) simultaneously, ensuring reliable data for PM2.5, PM10, and TSP monitoring during peak smog seasons.
7-in-1 Comprehensive Detection & TSP Monitoring
A versatile power player for environmental compliance. This handheld monitor tracks PM1.0, PM2.5, PM4.0, PM10, TSP, and particle counts. It is specifically designed to meet the rigorous standards of pharmaceutical labs, electronics manufacturing, and cleanroom ISO verification.
Rugged All-Metal Construction for Site Durability
Unlike plastic monitors, the PMD371 features a robust aluminum alloy housing that offers superior anti-interference and impact resistance. It is built to withstand the harsh, dusty environments of construction sites, mining operations, and industrial workshops.
Massive 2 Million Data Points & Easy Export
Equipped with a massive 8GB internal memory, it can store up to 2,000,000 sets of data. Seamlessly export logs via USB or RS-485 (Modbus RTU) to generate professional compliance reports for environmental consultants and factory auditors.
Extended 8-Hour Battery Life & Field Portability
Powered by a high-capacity rechargeable lithium battery, providing up to 8 hours of continuous operation on a single charge. Its ergonomic, handheld design allows for easy mobile monitoring across different field sites from Delhi to Mumbai without frequent recharging.
