All Rain-O-Matic Professional and Meteorological rain gauges have been carefully calibrated at the factory, but readjustment can easily be made. 
Pronamic offers to recalibrate all Rain-O-Matic products for 300 DKK/41 €uro per unit ex. shipping charges. 

With every recalibration, the rain gauge and components are getting cleaned and there will be issued a signed calibration certificate.

How to calibrate your rain gauge

You can also recalibrate it yourself in the following way: 

  1. Weigh or measure exactly 0,5 liter (500 cm³) water. Drip the water very slowly into the funnel over a period of about 30 minutes.
  2. By an Allen key S2 the adjustment screw – visible under the spoon – can be turned. If the screw is turned clock-wise, the display of the counter is positively influenced. If the screw is turned anti-clock-wise, the display is negatively influenced.

If the display does not show the required numbers of digits, further adjustment should be made by repeating the process described above.

On all our Meteorological models it is possible to collect the registered rain for a test measuring. The rain runs from the funnel into the measuring spoon and then through the drain pipe which is mounted in the flange. The water can be collected in a measuring glass for control measurement and laboratory test.
