KH.JDW Windproof Tipping Rain Sensor for High-Precision Coastal Island and Harsh Environment Rainfall Monitoring
Automatic Precipitation Sensor for Meteorological Hydrological Smart Agriculture Flood Warning and Urban Water Management Applications
Product Introduction (pdf)
Product Introduction
The KH.JDW Windproof Tipping Rain Sensor is a high-precision rainfall monitoring instrument designed for meteorological, hydrological, and environmental applications in coastal, island, and high-wind regions. Equipped with a windproof flange and labyrinth drainage system, it delivers accurate and reliable precipitation measurements even under extreme weather conditions.
Its 304 stainless steel construction provides excellent corrosion resistance, UV protection, and long-term durability. Compliant with SL61-2003 and GB/T201978.2-2014 standards, the KH.JDW ensures stable real-time rainfall data for smart agriculture irrigation, flood warning, urban water management, and environmental monitoring systems.
Key Features
- Windproof Design: Special flange and structural layout maintain stable measurements in high wind conditions, preventing airflow-induced errors
- High-Precision Tipping Bucket: Rainfall resolution of 0.2 mm / 0.5 mm with measurement error ≤±4% ensures accurate and repeatable precipitation data
- Durable 304 Stainless Steel Body: Corrosion-resistant, UV-proof, and capable of withstanding harsh coastal and extreme weather environments
