Highly precise, flexible and handy instruments for measuring changes in radius, diameter, circumference and length of different plant parts (e.g. stem). SF-L: Highly accurate Sap Flow Sensor SF-G: The conventional thermal dissipation probe (TDP) developed by Granier. Extremely lightweight and precise sensors for continuous measurements of leaf-to-air temperature differences. Highly accurate and maintenance-free instrument for measuring soil matric potential (plant relevant availability

Why do we need dendrometers? Electronic dendrometers are highly precise instruments for the continuous measurement of changes in diameter, circumference or length of different plant parts (i.a. growth dynamic and diurnal diameter changes of tree stems or fruits). Dendrometer signals document the response of plants to their environment in high temporal resolution. In plant research the time scale of interest ranges between decades and minutes, depending on the specific research question. In contrast to other plant and environmental parameters that are measured with high temporal resolution (hourly...

DR Radius Dendrometer Delivery ■ Complete with 5 m cable Options / Ordering Information ■ Cable extension (please specify in meters) ■ Installation tools (tree resin, hand drill) ■ Data Logger The sensor is fixed by two special screws, anchored in the trunk wood. The changes outside of the trunk wood correspond to radial growth and diurnal diameter variation. The arrangement ensures high stability for long-term measurements. Advantages ■ Stability against wind, snow, falling branches and fruits ■ Low pressure at the measuring point ■ Suitable for large trees (diameter> 8 cm) ■ Ideal for long-term...

DD-S Diameter Dendrometer Small www.ecomatik.de 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 The DD-S is designed specifically for agricultural plants, small trees and branches (diameter < 5 cm). Due to the patented 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. Advantages ■ Suitable...

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 The DDW is the ruggedized version of the DD-L dendrometer type. In addition to the features of the simple DD-L version, the DDW dendrometer is modified for the use under especially harsh environmental conditions. A soft, weather-resistant rubber coating, protects the whole sensor from ingress of water and solid particles. Advantages (additionally to DD-L type) ■ Suitable for diameter...

DF Fruit and Vegetable Dendrometer The Fruit and Vegetable Dendrometer is the special dendrometer version for measurements on circular fruiting bodies. The fruit in the measuring frame is firmly fixed without affecting its growth. The frame sustains the weight of the target and relives the peduncle. Advantages ■ Suitable for diameter between 0 and 11 cm (other size on request) ■ Fruits do not have to bear the weight of the dendrometers ■ Measures diameter changes ■ Assessment of ripeness for softening fruit types ■ No Injury to fruits ■ Stability against wind, snow, falling small branches and...

DRO Root and Aquatic Plant Dendrometer Delivery ■ Complete with 5 m cable Options / Ordering Information ■ Cable extension (please specify in meters) ■ Data Logger The DRO Dendrometer is designed for continuous measurement of roots, aquatic plants and creepers. A soft, light resistant rubber coating protects the whole sensor from ingress of moisture, the device is waterproof. A metal clamp protects the sensor from excessive pressure exerted from overlying soil. The specific weight of the unit is similar to that of water. When used underwater, no extra load is charged on target plants by the floating...
