The Circumference Dendrometer is the simpler version for the measurement of circumference changes of plants.
This sensor is discontinued, we recommend the DC3 version improved. The elastic force of the sensor is not applied in tangential, but in radial direction
The DC3 has the same layout as the DC2. Only the sensor measuring range is greater than with the DC2. This meets the measurement requirements of fast- growing trees.
The diameter sensor is mounted with a patented fixture at the plant. The sensor remains stable fixed at the measuring point without exerting excessive pressure on the measuring point. The model is suitable for diameter of 3-30 cm.
The Radial Dendrometer 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.
◆ DF-series: Suitable for diameters between:0 to 13 cm (DF4)0 to 3 cm (DF5)0 to 5 cm (DF6)
The DL18 is a battery powered, weather proof, 4- channel data logger. It runs on an internal battery more than one year. It is suitable for long-term monitoring tree growth.
Mini-Systems with Data Logger DL18-BLE
The Radius Dendrometer DRW is the ruggedized version of the DR dendrometer.Additionally to the features of the simple DR version, the DRW dendrometer is modified for the use under especially harsh environmental conditions.
◆ Heat-pulse sap flow sensors (just as with TDP sap flow sensors) also work on a temperature-based measuring principles.◆ The difference however, is that HP sap flow sensor does not require continuous heating, but only a short heat pulse of a few seconds is applied.◆ Depending on the measurement method used, the direction-dependent propagation as well as...
LS 40 - LAT-C Leaf temperature sensor for conifer needles. Extremely lightweight. Direct, highly precise and continuous measurements of needle AND air temperature, range between -20 and +70°C. Spatial signal integration via multiple measurement points at the surface of several needles. Suitable for needle sizes > 3 mm length. Analogue sensor outputs...
Typical Granier Sap Flow Sensor with two needles. For trees with a diameters >2 cm.Sap flow sensors are used to continuously measure water uptake in trees and woody plants.The SF-G range corresponds to the classic two-needle model developed in 1985 by André Granier.It requires use of the CCS to feed the current.
Improved Granier Sap Flow Sensor with four needles and a much higher accuracy. For trees diameter >15 cm. It requires use of the CCS to feed the current.
