As highly precise and robust measuring instruments, electronic dendrometers are used to continuously record changes in the size of different parts of plants (e.g. trunk, branch, root and fruit of trees, as well as herbaceous plants). The micrometer-accurate dendrometer data obtained provides valuable information on vitality and growth dynamics, as well as on the water status of the plant. They can be used under all growth conditions (tropics, polar regions, underground, under snow or underwater). Their wide range of application, reliability and low maintenance, as well as extremely low power consumption make Ecomatik dendrometers a versatile and cost-effective tool in the fields of ecological research and agriculture.
