DR1 Radial Dendrometers
◆ The sensor is fixed by two special screws, anchored in the trunk wood.
◆ The changes outside of the trunk wood correspond to radial growth and diurnal diameter variation.
◆ The arrangement ensures high stability for long-term measurements.
Radius Dendrometer, type DR1, for tree diameter >8 cm
Measuring range: 11 mm
Linearity: 1%.
