Rain_Lb-e Lambrecht Rain (e) Sensor

The Rain[e] is a new type of weighing precipitation sensor: Highest resolution combined with the most compact design.

The unique self-emptying collection system enables the measurement of every single drop with the high resolution of 0.001 mm/m². Full functionality all year around without anti-freeze fluid makes the Rain[e] very environmentally friendly too. 

Rain[e] is easy to lift, transport, install and maintain. The small packing volume and the low weight ensure minimum logistical effort. 

NOTE: DC Power would need to come from a mains Power supply, due to the heater.
