Description
The most economical solution
It is a Tower rain gauge that measures the amount of rain fallen using a tilting bucket with automatic emptying. It has a reed switch that opens every time the weight of the accumulated water tilts the spoon, which produces a pulse that can be recorded using a datalogger or pulse counter. It is made of UV- and frost-resistant plastic.
Patented automatic emptying system
A magnet keeps the spoon in a balanced position, so that emptying occurs through a rapid movement of the tip, which immediately returns to the initial position to collect a new portion of water.
