Diameter Dendrometer small : DD-S | Ecomatik

The DD-S series dendrometers are used for high-precision and continuous measurement of stem diameter changes. These devices are suitable for long-term application in outdoor conditions. Due to their extremely low power consumption, Ecomatik dendrometers are ideal for battery-powered solutions, e.g.,in IoT applications. DD-S dendrometers are specially designed for small trees and branches as well as agricultural plants (diameter < 5 cm). The optimized device mounting enables stable installation without exerting excessive pressure on the measuring point. DD-S dendrometers thus deliver stable readings even on very small and herbaceous plants. DD-S dendrometers are available in three versions:

1. DD-S1: with standard mounting frame

2. DD-S2: with quick-mount frame

3. DD-S2W: with a quick-mounting frame and hermetically sealed to withstand extreme environmental conditions (under snow cover, underwater, elevated exposure to dust and corrosive agents)

Advantages of the DD-series

• Suitable for small trees and branches as well as agricultural plants with a diameter < 5 cm-Lightweight sensor
• Plants do not have to bear the weight of the sensor (requires a separate support accessory for very small and sensitive plants)
• Injury-free installation, minimal pressure on the plant
• Stability against wind, snow, falling branches and fruits

Specific to the DD-S2 & DD-S2W models

• Quick mounting frame for fast, easy and tool
• free installation ofthe measuring object

Specific to the DD-S2W model

Hermetically sealed to withstand extreme environmental conditions: e.g. high humidity, underwater, below snow cover, near the ground surface, elevated exposure to dust or corrosive agents (e.g. coastal sands and salt, volcanic ash), etc.

Limits of the DD-S series

Not suitable for diameters > 5 cm (see type DD-L)

Specific for the DD-S1 & DD-S2 models

Not suitable for operation under extreme environmental conditions: e.g. high humidity, underwater, below snow cover, near the ground surface, elevate dexposure to dust or corrosive agents (e.g. coastal sands, volcanic ash), etc.(see model DD-S2W)

What should you check before choosing this product?

Match the dendrometer geometry to the plant part and expected size changes. Check mounting clearance, measuring range and data logger compatibility before specifying the installation.
