Model DE-1P - Dendrometer Brochure

The DE-1P Dendrometer is a highly precise incremental LVDT-based sensor for monitoring micro-variations of trunk radius in micron range. Plant growth and water balance affect diurnal behavior of trunk radius. The growth rate depends on a vegetation stage and environmental conditions. The diurnal variations represent mostly fluctuations of water content in plants. Two radius-based indices are commonly used for evaluating plant water status: daily contraction amplitude and trend of daily maxima. The DE-1 Dendrometer allows investigating effects of irrigation rate and other environmental factors on water balance and growth of plants.
