The Davis model 6465 is an AeroCone rain

The Davis Model 6465 rain gauge is an AeroCone rain collector designed for accurate rainfall measurement, especially in windy conditions. It's a tipping bucket rain gauge with a magnetic switch, often used with Davis weather stations like the Vantage Pro2 and Weather Envoy. The 6465 model is known for its aerodynamic design, which helps reduce wind-induced errors, and its ability to be mounted on a pole or flat surface. 

Here's a more detailed breakdown:

Tipping Bucket Mechanism:

The 6465 uses a tipping bucket mechanism with a magnetic switch to register rainfall. As the bucket fills, it tips when it reaches a specific volume (e.g., 0.2 mm), triggering the switch to record the rainfall. 

AeroCone Design:

The rain collector features an aerodynamic cone that minimizes wind-induced errors, improving accuracy, particularly in windy environments according to the product description on Amazon.com. 

Mountable Base:

It comes with a base that can be mounted on a pole or a flat surface, providing flexibility in installation. 

Compatibility:

The 6465 is compatible with various Davis weather stations, including Vantage Pro2, Weather Envoy, and Vantage Connect. 

Accuracy:

The rain gauge is factory-calibrated and designed to meet World Meteorological Organization (WMO) guidelines. 

Components:

The 6465 includes features like a debris screen and bird spikes to prevent obstructions and ensure accurate measurements.
