Using the Bark Probe for measuring the thickness of bark ©

The Bark Probe is a tool of small size and weight for measuring the bark of eucalypt and other trees.

The probe is placed against the bark and the plunger struck lightly until the needle penetrates to the wood interface.

The user must "feel" or listen for the change as the needle reaches the woody material. Read the depth from the scale while the needle is still embedded in the tree.

Withdraw the instrument straight out from the bark to avoid bending or breaking the needle.

The measuring technique is virtually non-destructive and is simpler, more accurate and precise than most other commonly used techniques.
