What is the accuracy of the Rain gage?
The Hydreon Rain Gage is not as accurate as a properly maintained Tipping Bucket in ideal conditions. We do not claim an accuracy specification for the Rain Gage. The Rain Gage is very repeatable, and over a variety of conditions will yield an average result that is reasonably close to that of a tipping bucket. But, for any given rainstorm the result can be off by as much as 2:1 in either direction. The strength of the Rain Gage is that it works in many situations where a tipping bucket simply does not. That is, the Rain Gage is vastly more accurate than a tipping bucket that has ceased to work properly due to dirt or mineral deposit or mechanical difficulty, or a tipping bucket in a mobile application that is constantly giving false indications due to motion. The Rain Gage is more accurate for a small (but in some applications, meaningful) amount of rain, such as 0.01″, that will simply not register in a tipping bucket. This said, if you do not need the ruggedness of the Hydreon Rain
