Plant Growth

Dendrometers are used to precisely measure the growth of plants in response to other environmental factors. This data can be used at similar time intervals to other environmental parameters such as water or temperature to get a highly detailed understanding of growth.

Used for biophysical research and precision farming

Applications include:

  • Research on the growth processes of plants
  • Monitoring the water status of plants for research, irrigation control or the effects of local construction activities on the ground water table
  • Precise dating of events such as the beginning and end of growing season, or stress events such as frost
  • Estimation of the water content and water storage pools in plants (in combination with sap flow measurement the transpiration can be calculated continuously)
  • Water loss of fruits and vegetables during storage


High precision, low power, rugged design

These instruments have been designed to be used in the widest range of environments for unattended monitoring.

  • Measurement resolution up to 0.2 um
  • Compatible with Campbell Scientific and other third party dataloggers as well as Ecomatik's dedicated datalogger
  • Internal battery lasts more than 2 years
  • Ruggedised models suitable for use underwater or in harsh environments
  • Temperature compensated


Different models for different species

There are a range of models so you can measure the trunks of large trees, individual fruits, tiny stems, roots and even underwater.
