MDD12

High Precision Adjustable Dendrometer

Dendrometers are precision instruments which are used to measure the growth of trees with changing environmental conditions. Various insights into short term and long term tree growth patterns and physiology can be obtained using these high-resolution dendrometers.


Growth rings, seen as light and dark rings over the cross section of a tree trunk, are indicative of seasonal variation.


Research scientists study these growth patterns in detail with a view to establishing relationships between climate, water uptake, timber quality and growth rate over a long period of time. This kind of data is useful for irrigation scheduling, assessing site quality, and developing models of the main drivers of tree growth over short and long periods of time. Dendrometer is a perfect and reliable instrument to provide this range of information for research activities across the globe.


MDD12 is based on non-contact LVDT (Linear Variable Differential Transformers) technology, provides highest level of stability in a long term application. LVDT dendrometers, compared to other technologies is more robust, unaffected by rain or dust and has better resolution. MeasureX MDD12 dendrometers come with signal conditioner and options for 4/20mA, 0-10V or 0-5V output.
