Benefits of Ecomatik Dendrometers Dendrometers are instruments for continuous measurement of plant growth (changes of the plant diameter). Data of dendrometer document the reactions of plants to environment in high temporal resolution. ■ Protected by several patented techniques ■ Low power consumption, as more than one year records only with an internal battery ■ More than 15 years of worldwide use (more than 40 countries, polar regions, tropical, high mountain) ■ Resolution up to 0.2 microns (depending on data logger) ■ Temperature effect compensated ■ Large selection for different measurement...

www.ecomatik.de 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 anchored by two special screws in the heartwood. The changes outside of the heartwood correspond to the radial growth. The arrangement ensures high stability for long-term measurements. Technical specifications Benefits ■ 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 measurement with...

DD-L Diameter Dendrometer Large 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 Technical specifications The sensor is mounted on a patented fastening technology at the plant. The sensor remains stable fixed at the measuring point without exerting too much pressure on the measuring point. The model is suitable for diameter of 3-30 cm. Diameter Dendrometer Large (DD-L) Suitable for plant size Diameter 3-20 cm (on request...

www.ecomatik.de Options / Ordering Information ■ Cable extension (please specify in meters) ■ Extension of the wire cable (please specify in meters) ■ Free Excel program for data conversion ■ Data Logger Technical specifications The DC2 is the improved version of the DC1. The tension is not applied in a tangential, but in the radial direction. The pressure of the wire cable to the tree is independent of tree size. The data of different tree sizes are comparable. The sensor is mounted on a wire cable with very low thermal expansion coefficient at tree. The slide rings reduce the friction between...

DF Fruit and Vegetable Dendrometer 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 Fruit and Vegetable Dendrometer is the special version for circular targets. The fruit in the measuring frame is firmly fixed without affecting its growth. The frame bears the weight of the target. Benefits ■ Suitable for diameter between 0 and 11 cm (other size on request) ■ Fruits do not have to bear the weight of the dendrometers...

www.ecomatik.de Delivery ■ Complete with 5 m cable Options / Ordering Information ■ Cable extension (please specify in meters) ■ Data Logger Technical specifications The DRO Dendrometers is designed for continuous measurement of roots, aquatic plants and creepers. The device is waterproof. The sensor rod is protected with soft, light resistant rubber. The metal clamp protects the sensor from excessive pressure from top soil. The unit has specific weight similar to water, when used under water therefore has no impact on plants. It is easy to install and maintenance free. By more than 1 year test,...

Data Logging and Communication ECOMATIK dendrometers are compatible with all popular data loggers (e.g. Campbell, Delta-T, DT80). We give you support for connecting our dendrometers with the data loggers. ECOMATIK provides a wireless data logger and den dendrometer data logger DL15. The Wireless Data Logger: Logs and wirelessly transmits real-time data to your computer, suitable for intensively monitoring tree growth in small area (green house, nursery). www.ecomatik.de Technical specifications Name Dendrometer Data Logger (DL15) 64 Kb (43 000 readings) If you connect 4 dendrometers, and collect...

● Continuous monitoring of sap flow in trees ● Improved “well known” Granier Sap Flow Sensor ● Accurate measurement of night-time sap flow ● Enhanced accuracy and reliability ● Simplified data processing ● Complete installation tools Introduction The well known Granier sap flow sensor, i.e. thermal dissipation probe (Granier, 1985) uses heat as a tracer of sap flow. Due to its simplicity, reliability and affordability, several scientists have used the Granier technique all over the world. However, the technique has always had some shortcomings, which include: 1). Granier technique determines...

Radial Increment Granier Sensor Fig. 3 Above: Air humidity and radial changes of a 40-year old spruce tree measured with an Ecomatik dendrometer type DD. Increase in diameter at night indicates that the tree continues to take up water even during nighttime hence sap flow is not zero. Below: Comparison between sap flow measured with Granier sensor (red line) and with SF-L sensor (blue line). The Granier sensor shows zero sap flow every night while the SF-L detects zero value only on the night of 9. July, when air humidity reached 100% and the tree body fully saturated with water.
