Integrated design with ventilated radiation protection for measuring: Air temperature, relative humidity, precipitation intensity, precipitation type, precipitation quantity, solar radiation, lightning detection, air pressure, wind direction and wind speed. One external temperature sensor is connectable.

  • First and only all-in-one compact weather sensor with lightning detection
  • Built-in data pre-processing, universal interfaces and selectable output protocols
    SDI-12 and RS485 interfaces
  • Maintenance-free operation – no moving parts to wear out
  • Suitable for all climate zones; also for solar-powered automatic meteorological stations
  • Integrated heater that can be switched on if there is danger of frost
