Precise stem diameter records

Diameter P DS data

no effect on tree growth

efficient tool for field measurement

comprises information about growth, water stress and freezing up of the stem

low maintenance and energy requirements in comparison with sophisticated measuring systems like sap flow for instance

together with the measurement of soil water potential 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
