Diameter Dendrometer Small - Type DD-S2
1
1. Introduction
Thank you for purchasing an Ecomatik Dendrometer type DD-S2. This is a highly precise
sensor for continuous measurements of diameter changes of small plants under both in-
door and outdoor conditions. The DD-S2 is designed for a fast and toolless installation.
This manual is written to help you install and operate your DD-S2 dendrometer with least
difficulty and for 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 den-
drometer should be connected to a data logger for continuous data recording. The den-
drometer is compatible with the most data logger types. At Ecomatik a low-cost, special
for dendrometers developed DL18 logger is available
