Outdoor Air Quality Monitor
Outdoor Air Quality Monitor from Tongdy is a professional environmental monitoring system designed for real time, multi-parameter outdoor air quality measurement in urban environments, industrial areas and infrastructure projects.
Note: All Tongdy monitors and controls ship direct from the factory. Please allow 10-15 business days for shipping and handling.
The system integrates commercial grade sensing modules capable of measuring multiple environmental parameters simultaneously while providing reliable data communication for smart city monitoring networks environmental compliance and research applications.
Modular design allows monitoring of up to eight environmental parameters including particulate matter gases temperature humidity and atmospheric pressure. Multiple communication options including RS485 WiFi Ethernet and 4G enable seamless integration with environmental monitoring platforms and IoT systems.
Engineered for continuous outdoor operation, the unit features a weather resistant enclosure with IP53 protection and integrated shielding against rain snow UV radiation and extreme temperatures. The monitor can be mounted on building walls rooftops poles or ground stations making it ideal for environmental monitoring networks and smart infrastructure deployments.
