Dendrometer: well-proven measuring instruments in ecological research

    Efficient tools for new applications in modern precision agriculture

    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.

    Areas of application

    • Monitoring of plant growth processes
    • Studies exploringhow environmental factorsinfluenceplant growth
    • Precise dating of the beginning and end of the growingseason
    • Precise dating of frost eventsMonitoring of plantwater status, e.g.
      in the context of:
      -ecological research
      -automated irrigation
      -construction activities
    • Plant water content and water storage estimations
    • Monitoring of static characteristics and stability of entire trees or individual branches, e.g. in forests, on roads or in parks
    • Data-based crop yield forecasts
    • Monitoring of water loss from fruits and vegetables during storage.
    • Measurements: radius, diameter, circumference, fruit, vegetables, vertical changes

    Technical features

    • More than 15 years, successfully used in more than 60 countries worldwide (polar regions, tropics, high mountains)
    • Very high measurement resolution up to 0.2 μm (depending on the respective data logger)
    • Extremely low power consumption withyears of battery life, e.g. in IoT applications
    • Special sensor design for minimal temperature drift
    • Compatible with almost all common data loggers and microcontrollers with analog voltage input channels (e.g. also Arduino)
