Do you want to know how much rain has fallen in your own backyard? This analog rain gauge can measure the amount of rain from 0 to 40mm/m2. As rain falls, the gauge cup will fill up to a maximum of one liter that allows the user to determine the daily rainfall on the simple to read scale. It has a revolving ring that manually records the amount of rain that has fallen in the given period. Just mount it on a pole, fence, or deck rail. Make sure they are easy to access and should not have any obstructions that could impact the accuracy of the reading.
