Description
Maximum precision
The rain gauge accurately measures the amount of rain that has fallen using an automatically emptying tilting bucket. 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 specially designed to comply with the guidelines established by the World Meteorological Organization (WMO).
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.
Robust, weather-resistant design
The instrument features a robust design and is made entirely of corrosion-resistant materials to ensure maximum durability.
Mounting options
The rain gauge can be installed at different heights as necessary, either on a hard surface or nailed to the ground using the optional fixing bases. The optional anti-bird crown prevents birds from landing on the mouth of the funnel.

ASA (Acrylonitrile Styrene Acrylate)
The rain gauge made in molded thermoplastic, also known as ASA, which has high outdoor weather ability. ASA is extremely resistant against the sun’s UV radiation, it is frost‐ and heat resistant, standing
all climatically conditions. The product is widely used in the automotive industry as well as several other outdoor applications.
PCB
The electronic printed circuit board with individually tested and high-quality reed switches protected against extreme weather conditions such as extreme frost or heat. This include corrosion from salt water due to the PCB is coated with weather‐ resistant varnish.
