Concentrate on the Size
If you are uncertain about the capacity, you should select the big one. It may cost you a little bit more, but the extra costs are needed if you want to attain maximum precision. In addition to having the primary collection location of 200 cm2, the larger size has some other benefits over its little sibling, such as much better resistance to heavy rains and less evaporation.
There are numerous variations of the rain gauge out there and selecting the right one can be difficult. They are typically made from stainless steel, aluminium and polycarbonate. All of them are great, but the latter is essentially impervious to severe temperature levels, bumps and falls.

Environment or Setting
The wind is the main hindrance to reliable rain data, so prevent positioning your rain gauge Australia in a windy location such as the top of a building.
