Radius dendrometer (DR)
The sensor is anchored by two special screws in the heartwood. The changes outside of the heartwood correspond to the radial growth. The arrangement ensures high stability for long-term measurements.
Advantages
Stability against wind, snow, falling branches and fruits
Low pressure at the measuring point
Suitable for large trees (diameter> 8 cm)
Ideal for long-term measurement with less manpower
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)
