Minimum energy consumption

rain[e] is a new type of weighing precipitation sensor: Highest resolution combined with the most compact design. The Low Power (LP) version of the sensor is the ideal choice for solar or battery powered applications. 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 antifreeze fluid makes the rain[e] very environmentally friendly.

rain[e]LP is easy to lift, transport, install and maintain. The small packing volume and the low weight ensure minimum logistical effort. The rain[e] series is compatible with OTT and Campbell Scientific data loggers and ideal for setup and expansion of rainfall measurement networks.

  • 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
  • installation and maintenance are very simple
