With larger collection surface

Latest weighing technology combined with a self-emptying precision tipping bucket allows the rain[e]400 a high resolution and high precision at a very small construction volume.
Already the first drop will be measured! The rain[e] is ideal to setup new measurement network as well as addition to an existing rainfall measurement network.  

  • Amazing resolution and accuracy
  • Checking of sensors with tipping bucket and other weighing systems
  • Compact and robust construction with a very low weight
  • All-metal housing, weatherproof and durable
  • Best connectivity by several interfaces
  • Installation and maintenance are very simple

Tretjakov-style Wind Shield · for precipitation sensorsTretjakov-style Wind Shield for precipitation sensors

A Tretjakov-style wind shield surrounds a precipitation sensor to block approaching winds. The funnel-shaped design ensures excess wind is directed toward the ground, reducing the speed of winds in the direct vicinity of the sensor.

The wind shield ring is equipped with vertical stainless steel lamellas arranged in a circle with the bottoms coming together in a slightly conical fashion. The lamellas are connected to each other with a chain, and can be moved horizontally to create directional protection.

 The Tretjakov wind shield consists of a frame, metal segments and accessories for quick and easy installation.

  • Different measuring heights for all common precipitation sensors
  • Durable and solid due to corrosion-resistant V4A stainless steel
  • Straightforward and quick installation
