French national meteorological approved rain gauge - Patented SDGGN° 1269277 with direct reading

The rain gauge consists of two interlocking plastic parts and a test tube.

1- The upper part of the rain gauge is opaque, in the shape of a funnel with a perforated bottom, and serves to collect rain over an area of 400 cm², which is very precisely defined thanks to its bevelled edge. The angle of this funnel is designed to reduce the splash of rain outside the reception area to a minimum.

2- The lower part of the rain gauge is transparent, stores the collected water and indicates the height of the rainfall by direct reading on a graduated scale:

  • in millimetres for rainfall between 0 and 10 mm with an approximation of 1/4 millimetre
  • in centimetres for rainfall between 1 and 10 cm, with an approximation of 1/2 millimetre. This approximation is sufficient for rainfall of this magnitude

3- The rain gauge test tube is graduated in mm and is subdivided into tenths of mm up to 8.2 mm (328cm3). Just below this division there is a small hole of 4 mm diameter so that the excess water collected above 8.2 mm can flow into the bucket. The advantages of installing the test tube in the bucket are fourfold

  • reduction of evaporation due to the double wall
  • reduction of the evaporating surface of the collected water
  • elimination of wetting errors due to decanting
  • high measuring accuracy
