Radius dendrometer rugged (DRW)

The DRW is the ruggedized version of the DR dendrometer type. Additionally to the features of the simple DR version, the DRW dendrometer is modified for the use under especially harsh environmental conditions. A soft, weather-resistant rubber coating, protects the whole sensor from ingress of water and solid particles.


Advantages (additionally to DR type)

  • Suitable for measurements underwater, under snow cover and under heavy exposure to dust (e.g. volcanic ashes or desert dust, etc.)

  • Suitable under exposure to corrosive seawater spray


Limits

  • Trunk is injured by drilling (the damage can be minimized by tree resin)

  • Suitable only for larger trees (diameter > 8 cm)


Delivery

Complete with 5 m cable


Options / Ordering Information

  • Cable extension (please specify in meters)

  • Installation tools (tree resin, hand drill)

  • Data Logger
