EWS Tipping Bucket Rain Gauge

Stainless-steel tipping bucket rain sensor.

EWS's Tipping Bucket Rain Sensor was originally designed for the National Weather Service to provide a reliable, full stainless-steel tipping bucket rain sensor.

It has been updated and improved with the addition of an inner funnel to even the flow of the rainfall into the gauge, providing better accuracy at higher rainfall rates. Its simplicity of design assures trouble-free operation, yet provides accurate rainfall measurement.
