A robust and accurate tipping bucket rain gauge series with flexible outputs for meteorological and environmental monitoring.
| Datasheet |
Product Description
The RTD Series Rain Gauges are designed for accurate measurement of rainfall intensity and accumulation using a tipping bucket mechanism, fully aligned with WMO No. 8 recommendations.
Rainwater is collected through a corrosion-resistant funnel and directed into a calibrated bucket that tips when a predefined volume is reached, generating an electrical pulse for precise rainfall calculation. The series offers multiple configurations, including different collector areas, resolutions, output types, and heated versions, making it suitable for a wide range of applications.
Built with durable materials and integrated diagnostic sensors (temperature, humidity, pressure, tilt), the RTD series ensures reliable operation and easy maintenance in long-term outdoor installations.
