Integrated design with ventilated radiation protection for measuring: Air temperature, relative humidity, air pressure, wind direction and wind speed. One external temperature or rain sensor is connectable.

  • All-in-one housing concept of a compact weather sensor combining 5 measurement parameters in one housing with only one cable connection
  • Built-in data pre-processing, universal interfaces and selectable output protocols
  • SDI-12 and RS485 interfaces
  • Maintenance-free – no moving parts to wear out
  • Ventilated temperature and humidity measurement according to WMO guidelines
  • Integrated heater that can be switched on if there is danger of frost
