Overview
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 are designed for continuous plant growth measurements and available in three configurations:
- DEN1 for DBV60 Band Dendrometer (maximum 5 sensors)
- DEN3 for DEX fruit dendrometers (maximum 4 sensors)
- DEN6 for Ecomatik Dendrometers (maximum 5 sensors)
Features
Details
The DEN1 can support up to 5 DBV60 sensors.
The DEN6 can support up to 5 Ecomatik Dendrometer sensors.
