Description
Met One – NPM 3 Network Particulate Monitor is a compact, low-power air quality monitoring solution designed for continuous measurement of particulate matter in networked environments. Using a forward light scatter laser nephelometer, the NPM 3 delivers accurate and stable measurements across PM1.0, PM2.5, and PM10 size fractions with a wide measurement range and high sensitivity. Its brushless diaphragm pump, long-term optical stability, and automatic humidity control ensure reliable performance in normal ambient conditions, even during extended outdoor operation.
Built with modern monitoring needs in mind, the NPM 3 features true plug-and-play functionality and seamless network integration, making it ideal for IoT applications, smart cities, and neighbourhood air quality monitoring. Compatibility with COMET Cloud Plus and CCS+ allows real-time data access across smart devices, while the weather-resistant design, low power consumption, and 24-month service interval reduce maintenance requirements. With excellent accuracy, flexible calibration via “K” factor adjustment, and an affordable price point, the NPM 3 offers an efficient and scalable solution for distributed particulate monitoring networks.
