DR radius dendrometer
This sensor for recording the tree trunk growth is particularly distinguished by its stable installation. It is anchored in the heartwood using two screws and in this way measures the change outside the heartwood as radial growth.
This arrangement guarantees both that long-term measurements are very stable and that the fastening is secure. There is only very little counter pressure created on the measurement point itself so that the radial growth is not obstructed by the sensor. Damage to the tree caused by the necessary drilling can be minimised using tree resin. The instrument is connected to an external data logger to record the data. This enables it to also be connected to an existing data logger to expand existing measurement stations. The radius dendrometer is supplied with 2 m of cable as standard. Cable extensions are available on customer request.
- Stable fastening offers resistance to wind, snow, falling branches and fruit
- Long-term stability reduces the need for maintenance and man-power
- Little pressure on the measurement point
