Fruit Dendrometer
– Type DF6
1
1. Introduction
Thank you for purchasing an Ecomatik Dendrometer type DF6. This is a precise sensor for
continuous measurements of fruit and vegetable diameter under both indoor and outdoor con-
ditions.
This manual is written to help you install and operate your DF6 dendrometer with least difficul-
ty and for most desirable results. Please read it carefully before installing the sensor, and refer
to it if you should have any difficulty with the sensor in the future.
The dendrometer is the sensor part of a measuring system. This means that the dendrometer
should be connected to a data logger for continuous data recording. The dendrometer is com-
patible with the most types of data loggers and microcontrollers (i.a. Arduino).
2. Product Description
As shown below, the DF6 dendrometer consists of:
1x Sensor with quick-mount fruit gripper hook, 5 m cable
1x Piece re-usable UV-resistant rubber reusable to fix the sensor cable at the branch/stem for
strain relief (rubber cord may also be delivered as separate part of a bulk delivery. Then the
total length may be delivered in one piece on a roll and).
1x Piece re-usable string cord to hang sensor to release the instrumented fruit from additional
sensor weight.
2x Cable strips to fix string cord to fruit carrying branch (for correct installation of the strips
please refer to the below section
“Installation”)

The standard cable length is 5 m. if you ordered cable extension, the cable length is the or-
dered ext 5 m.

Safety Information
The sensor is protected from rain water, but it is not sealed. Please do not immerse the sensor
