Product Introduction

The KH.JD Series Windproof Tipping Rain Sensor is a high-precision precipitation monitoring instrument designed for coastal and island environments. Unlike traditional tipping bucket rain gauges, it features a windproof flange and labyrinth drainage system to ensure accurate rainfall measurement even under high wind and extreme conditions.
Compliant with SL61-2003 Hydrological Automatic Weather System Specification and GB/T201978.2-2014 Precipitation Observation Instrument Standard, this sensor is ideal for meteorological rainfall monitoring, hydrological stations, and environmental observation projects.

Features

• Windproof Structural Design: Specially designed flange ensures stable measurement in high wind conditions.

• High Precision Measurement: Rainfall resolution of 0.2mm or 0.5mm with an error rate ≤±4%.

• Durable Outdoor Materials: Constructed with 304 stainless steel, resistant to corrosion, UV, and extreme weather.

• Labyrinth Drainage System: Prevents water accumulation and improves measurement accuracy.

• Reliable Switching Output: Dual dry reed switch generates accurate rainfall pulse signals.

• Wide Operating Range: Operates stably from -20℃ to +60℃ with ≤95% RH humidity.

• Standards Compliance: Fully meets hydrological and meteorological monitoring requirements.
