ir Quality Sensor PM2.5 PM10 Transmitter – High-Precision Dust Detector The Air Quality Sensor NEX-3001-PM is a professional-grade PM2.5 and PM10 transmitter designed for real-time dust concentration monitoring in indoor and outdoor environments. With its advanced pump-type probe and high-sensitivity detection technology, it delivers precise, stable, and reliable data for air quality management, environmental research, and industrial safety applications. [ez-toc] Key Features of the Air Quality Sensor 1. Wide Measuring Range The Air Quality Sensor offers a wide detection range, ensuring accurate measurements across varying particle concentrations. Whether used in urban environments, laboratories, or industrial sites, it consistently captures reliable PM2.5 and PM10 data, essential for assessing pollution levels and compliance with air quality standards. 2. Advanced Pump-Type Probe Unlike traditional diffusion-based designs, this sensor uses a pump-type air sampling system. Air is actively drawn into the probe via a precision fan, which significantly enhances response time and improves measurement accuracy. This makes the transmitter ideal for applications requiring real-time, high-frequency monitoring of dust particles. 3. High Sensitivity and Stability Equipped with a high-sensitivity gas detection probe, the device delivers stable and consistent readings even in low or fluctuating concentration levels. It minimizes signal drift over time, providing dependable long-term monitoring results. 4. Durable ABS Material Constructed from industrial-grade ABS, the Air Quality Sensor is resistant to impact, heat, and environmental corrosion. This ensures durability and consistent operation even under harsh conditions, making it suitable for factories, warehouses, and smart-city deployments. 5. Wall-Mounted Design The compact, wall-mounted design provides a clean and efficient installation option. It saves space and allows for continuous air quality monitoring without obstructing other equipment or workspaces.
