Dendrometer DRL26D

► The sensor is designed for quick and easy installation. It is secured to the object to be measured using a stainless steel strap wrapped around the stem.

► The adhesion pressure is established as a balance between the influence on plant tissues and position stability.

► Installation Notes:

● The sensor should be placed on a relatively straight and evenly shaped part of the stem, in a relatively smooth location with no irregularities in the circumference. The sensor base should sit firmly on all four points. For more information, see the installation manual.
