Optimal logging solution: Dendrometer
Other Dendrometers: DR26
DRL26 Logging Band Dendrometer
Accurately measure and monitor tree growth ratesWhole tree water relations research has just become easier and more accurate. The logging band Dendrometer now incorporates its own self-contained datalogger. Using an internal lithium battery there is no need for external batteries or solar panels to power the logger, meaning it can be attached to a tree and set logging with no other accessories or requirements.
Such independence means multiple trees throughout an experimental site can be continuously logged over a much larger area than if they were required to be connected to a central logging system. Small trees, large trees, neighbouring trees or very distant trees can now easily be measured without physically limiting design constraints. The DRL26 logging dendrometer is a very reliable and low cost method of accurately measuring and monitoring tree growth rates.
More Details
Tree growth rate data becomes more accurate because a larger spatial average can be made as well as replication across a large range of trees sizes. The data collected is of the highest accuracy with a measurement resolution of 1 micron in stem diameter change. Such resolution accurately allows for interpretation of diurnal stem fluctuations in response to climatic and micro-environmental effects in addition to long term growth.
Diurnal stem fluctuations data can then be combined with sapflow data from the same tree to correlate water use to further understand functional hydrology of the tree and or specific treatment effects.
Features
The DRL26 features a non-invasive attachment to the tree using a rotary position sensor to make a step-less reading of stem diameter and growth. The built in datalogger has a memory capacity of 50,000 readings which, at hourly logging intervals provides 4 years worth of data storage. The internal lithium battery ensures 5 years operation at the same hourly logging interval. The logger is environmentally sealed utilising an Infrared communications link, completely removing the worst waterproofing weak spot of any logger, the serial port. Finally, a MS Windows-based software package allows configuration of the logger plus detailed statistical analysis of the data making the DRL26 the only solution for dendrometry research.Features
