Model DATARAIN-4000 is a professional precipitation sensor designed by GEONICA according to the requirements of the WMO (World Meteorological Organization).
This precipitation sensor combines a very accurate measurement principle (electronic weighing) and an automatic emptying system, in such a way to allow a reliable and low-maintenance operation.
Due to its principle of operation, the sensor provides permanent calibration, and its resolution and accuracy are also maintained in the whole measuring range (up to 2000 mm/h precipitation intensity).
The upper limit of the intensity range of the smart precipitation gauge DATARAIN-4000 largely exceeds natural phenomena. Two different models of DATARAIN-4000 are available whose only difference is their collecting are: 200 cm2 or 400 cm2. A built-in temperature probe allows a self-managed energy-efficient heating control when the optional two heaters are included.
