Diameter Dendrometer small (DD-S)

The DD-S is designed specifically for agricultural plants, small trees and branches. It is suitable for plants with a diameter of less than 5 cm. Due to a patented mounting method, the dendrometer provides stable readings also for very small diameters.


  • Suitable for small trees and agricultural plants
  • The plants do not have to bear the weight of the dendrometer
  • Measures diameter changes: as compared with radius measurements the doubled measurement signal results in higher precision
  • 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 5 cm (please see Typ DD-L)


  • 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
