The Circumference Dendrometer 1 is the simpler version for the measurement of circumference changes of plants. The sensor is mounted on a wire cable with a very low coefficient of thermal expansion on the plant. The slide rings reduce the friction between the wire cable and the tree bark. They also decrease the pressure of wire cable on the tree.
Please note the essential difference between the various circumference dendrometers.
Suitable for diameter 5-30 cm
No injury to plants
Stability against wind, snow, falling small branches and small fruits
Readings directly correspond to the circumference changes
