DEN Dendrometer Sensor Meters
Dendrometer Sensor Meters are designed for continuous plant growth measurements and available in three configurations
Measuring plant growth over a continuous basis will provide crucial information for resource optimisation (eg, water, fertiliser) during the plant growth period. .
The DEN range of Dendrometer Sensor Meters share a common logger configured for each sensor type. All loggers store data on a local microSD card for downloading for analysis on a local computer.
The DEN Dendrometer loggers are available in the following configurations:
- DEN1 for DBV60 Band Dendrometer (maximum 5 sensors)
- DEN3 for DEX fruit dendrometers (maximum 4 sensors)
- DEN6 for Ecomatik Dendrometers (maximum 5 sensors)
