Fruit and Vegetable Dendrometer (DF)

The DF is the special dendrometer version for measurements on circular fruiting bodies. The fruit in the measuring frame is firmly fixed without affecting its growth. The frame sustains the weight of the target and relives the peduncle.

Advantages

  • Suitable for diameter between 0 and 11 cm (other size on request)
  • Fruits do not have to bear the weight of the dendrometers
  • Measures diameter changes
  • Assessment of the time point of ripeness for softening fruit and vegetable types
  • No Injury to fruits
  • Minimal load on the target
  • Stability against wind, snow, falling small branches and small fruits

Limits

  • Not suitable for oversoft fruit types (such as ripe raspberries)

Delivery

  • Complete with 5 m cable
  • Fixing materials and installation tools (wrench)

Options / Ordering Information

  • Cable extension (please specify in meters)
  • If necessary, different frame size
  • Data Logger
