Non invasive fixing by tape
no effect on tree growth
integrated value for whole radial profile in measured height
almost identical thermal expansion of wood and stainless steel
Precise increment records
efficient tool for field measurement
comprises information about growth, water stress and freezing up of the trunk
low maintenance and energy requirements compared to sophisticated measuring systems such as sap flow for instance
together with soil water potential measurement it gives realistic picture of drought stress and the tree response to it
SDI-12 data output
asynchronous serial communications protocol for intelligent micro-processor based sensors
sensor typically takes a measurement, makes computations based on the raw sensor reading, and outputs the measured data in engineering units
allows connection of set of sensors serially on one cable line
