DD Ecomatik Diameter Dendrometers (S-L Stems)
Diameter Dendrometers
Ecomatic Diameter dendrometers are designed specifically for measuring changes in diameter in agricultural plants, small trees and branches (diameter <5cm).
Due to the optimized mounting method, the dendrometer provides stable readings also for very small plants. The sensor remains stable fixed at the measuring point without exerting excessive pressure on the measuring point.

Diameter Dendrometers (Small)
The DD-S Type dendrometers are designed specifically for agricultural plants, small trees and branches diameter <5cm). Due to the optimized mounting method, the dendrometer provides stable readings also for very small plants. The sensor remains stable fixed at the measuring point without exerting excessive pressure on the measuring point. The sensor is available in two versions: DD-S1 with standard mounting frame, DD-S2 with quick mount frame.
Advantages
- Suitable for small trees and agricultural plants
- Plants do not have to bear the weight of the dendrometer (with separate support construction for very small and delicate plants)
- No injury to plants
- Minimal contact pressure on the plant
- Stability against wind, snow, falling small branches and small fruits
- Plant size specific ordering possible within the 0 to 5 cm diameter range
Limits
- Not suitable for diameter greater than 5 cm (see Type DD-L)
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
Diameter Dendrometers (Large)
DD-L type dendrometers are mounted at the plant with two elastic, and uv-resistant rubber belts. With this easy and very stable fixation, the sensor remains at the desired measuring point, without exerting excessive pressure on the stem. The sensor is available in three versions: DD-L1 with standard measuring range of 11mm for slow and normal growing species and DD-L2 and DD-L3 with increased measurement range of 25mm and 50mm respectively, for fast growing species. Both models are suitable for stem diameters between 3-30cm.
Advantages
- Suitable for diameter 3-30 cm
- No injury to plants
- Minimal load on the target
- Stability against wind, snow, falling small branches and small fruits
- Plant size specific ordering possible within the 3 to 30 cm diameter range
Limits
- Not suitable for diameter greater than 30 cm
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
