Non invasive fixing by tape

D RL 26 C non-invasive fixing
  • no effect on tree growth
  • integrated value for whole radial profile in measured height
  • almost identical thermal expansion of wood and stainless steel

Precise increment records

Dendrometer data
  • efficient tool for field measurement
  • comprises information about growth, water stress and freezing up of the trunk
  • low maintenance and energy requirements compared to sophisticated measuring systems such as sap flow for instance
  • together with soil water potential measurement it gives realistic picture of drought stress and the tree response to it

Measure trees with different diameter by simple changing the base plate
