Diameter Dendrometer Large (DD-L)

The sensor is mounted on a patented fastening technology at the plant. The sensor remains stable fixed at the measuring point without exerting too much pressure on the measuring point. The model is suitable for diameter of 3-30 cm.


  • Suitable for diameter 3-30 cm
  • Measures diameter changes, higher precision than with radius measurements
  • No Injury to plants
  • Minimal load on the target
  • Stability against wind, snow, falling small branches and small fruits
  • Ordering by size of plants possible


  • Not suitable for diameter greater than 30 cm


  • Complete with 5 m cable
  • Fixing materials and installation tools (wrench)

Options / Ordering Information

  • Cable extension (please specify in meters)
  • If necessary specify frame size in case of differing plant diameter
  • Data Logger
