Small Weather Station

Product Introduction:

Seven Elements Weather Station-Multi-parameter Automatic Weather Monitoring Instrument Equipment is a high-level professional meteorological system designed mainly for the national weather forecast business data source. This system adopts standard structure and process modular design, and has the advantages of high precision/full automatic/maintenance-free/high integration, and is suitable for long-term operation in various harsh environments. At the same time, the monitoring data can be directly entered into the national meteorological observation network to provide accurate data guarantee for meteorological services.
