Advantages of the Smart Weather Sensor WS600

  • Measuring wind direction and speed insusceptibly to bird nesting thanks to roofed construction
  • All-in-one housing concept of a compact weather sensor combining 6 measurement parameters in one housing with only one cable connection
  • Built-in data pre-processing, universal interfaces and selectable output protocols
  • Compatible with many commercially available Met/HydroMet dataloggers and PLS systems thanks to an open communication protocol
  • Maintenance-free operation – no moving parts that can wear out
  • Suitable for all climate zones; also for solar-powered automatic meteorological stations
  • Ventilated temperature and humidity measurement according to WMO guidelines
  • Integrated heater that can be switched on if there is danger of frost.
