The Rain-O-Matic is an innovative product with a funcional design. This rain collector is conceived to be used outdoors and to connect it to a digital pulse counter.

For every mm of rain recieved by the rain collector, an automatic emptying device is activated. This is registered in the LCD counter by means of an impulse. By registering the number of impulses (=number of mm rain), the LCD counter records the total amount of rain received, which can be read off at any time on the LCD display.

Rain-O-Matic has been subjected to 2 years of demanding tests at the Danish Agricultural Testing Laboratory (Dansk Landbrugs Testlaboratorium) and the State Appliance Testing Institute (Statens Redskabsprøver)'s results have placed it among the world's most accurate rain-gauges.

Rain-O-Matic is frostproof, exceptionally reliable, and has an accuracy varying less than 2% over a 2-year period.
