Product Introduction

The KH.JDW Windproof Tipping Rain Sensor is a high-precision precipitation monitoring instrument designed for meteorological, hydrological, and environmental applications in coastal, island, and high-wind regions. Featuring a windproof flange and labyrinth drainage system, it ensures accurate rainfall 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 delivers reliable real-time rainfall data for smart agriculture, flood warning, environmental monitoring, and urban water management 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 and UV-proof, capable of withstanding harsh coastal and extreme weather environments.
• Labyrinth Drainage System
  Prevents water accumulation and ensures consistent, reliable rainfall readings.
• Reliable Switching Output
  Dual dry reed switch provides precise rainfall pulse signals compatible with IoT, SCADA, or data logging systems.
• Wide Operating Range
  Operates reliably from −20℃ to +60℃ with up to 95% relative humidity.
• Standards Compliance
  Fully compliant with meteorological and hydrological monitoring requirements for professional applications.
