DBH means tree diameter at breast height , also called stem diameter. DBH dendrometer is easy to use and measures diameter changes correctly.
Highlighted features:
It applies laser etching technology, makes the scale clear and easy to read, the scale will not disappear and remains clear after long time usage.
Stainless steel material will not rust in the field.
Measurement unit is π, so we can read diameter and diameter changes directly.
Use a spring to fix the device and no injury to plants after long term mornitoring
Vernier is integrated on main scale, minimize the whole size and easy to read value
Suitable for small plant perimeter down to 5π cm, other dendrometers only to 10π cm
