Service and support

Se all of the service and support pronamic offers listed below


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 175 DKK/23,65 €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.

You can also recalibrate it yourself in the following way: 
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.

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.
