Protected against freezing

Due to the innovative weighing technology combined with a self-emptying collection vessel the rain[e] sets new standards in professional precipitation measurement. Its outstanding resolution and accuracy are approved all over the world. The rain[e]H3 with electronically regulated ring heating is designed especially for extreme cold climates. Integrated outside temperature sensor, real time clock, electronic monitoring when opening the housing and remote servicing are features of continuous development. With optional port server and web interface the rain[e]H3 is well equipped for all communicative demands in future.  

  • electronically controlled ring-, funnel- and drain-line heatings
  • outstanding resolution and accuracy
  • all-metal housing, weatherproof and long-living
  • easy installation and maintenance

to reduce the measurement error due to wind influence.

In combination with the weighing precipitation sensor rain[e]H3, the Tretjakov windshield is used by the German Weather Service (DWD) at selected locations.

The windshield is equipped with vertically circularly arranged stainless steel blades. These segments are horizontally movable and are conically joined at the base of the precipitation sensor.

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