Tree stems and their respective sections vary in length and curvature, according to water status (short- to mid-term) wind direction and wind speed (short-term to permanent), snow and fruit load (mid-term to permanent), unbalanced growth or loss of crown parts (long-term to permanent). Vertical changes are a valuable information to assess water status and static characteristics, such as mechanical stress-strain relationships and mechanical stability of trees. In order to disentangle the different causes (water status, mechanical stress), parallel measurements with three vertical dendrometers, oriented in three different cardinal directions are necessary.


■ Assessment of mechanical stress-strain relationships

■ Suitable for large trees (diameter>8 cm)

■ Robust installation, resistant against wind, snow, falling branches and fruits


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


■ Complete with 5 m cable and 1 m wire cable

Options / Ordering Information

■ Cable extension (please specify in meters)

■ Installation tools (tree resin, hand drill)
