Description

Maximum accuracy

The rain gauge accurately measures the amount of rainfall by means of a self-emptying tipping spoon. It features a reed switch that opens each time the weight of the accumulated water causes the spoon to tilt, thus producing a pulse that can be recorded by a datalogger or pulse counter. It is specially designed to meet the guidelines established by the World Meteorological Organization (WMO).

Patented self-emptying system

A magnet holds the spoon in equilibrium position, so that the emptying is produced by a fast movement of the tip, which returns immediately to the starting position to pick up a new portion of water.

Rugged and weatherproof design

The instrument features a rugged design and is entirely made of corrosion resistant materials to ensure maximum durability. The design of the funnel allows rainwater to flow very effectively into the spoon, avoiding splashes and evaporation losses at the same time. The included removable filter prevents leaves, debris and other elements from clogging the funnel and blocking the passage of water.

Optional heater

It is activated automatically at temperatures around 4ºC, preventing the accumulation of ice and snow in the funnel and allowing precise measurements at low temperatures or during and after a snowfall.

Mounting options

The rain gauge can be mounted at different heights depending on the needs, either on a hard surface or nailed to the ground using the optional fixing bases. The optional bird spikes prevent birds from landing on the mouth of the funnel.
