Dendrometer sensor probes
Dendrometers are highly precise instruments for the continuous measurement of changes in plant diameter (i.e. growth dynamic, diurnal diameter changes). Dendrometer signals document the response of plants to their environment in high temporal resolution.This type of sensors do not measure the total diameter of the trunk or fruit, but the micro variations in diameter. That is a great tool to study how well the plant grows, absorbs and transpires water, its hydrological stress, possible diseases, etc.
