Forest Ohms Electrical Reistance - The Shigometer
Ohms (Electrical Resistance):
The Shigometer: This device measures electrical resistance (in ohms) by inserting a probe into the tree trunk.
ENDORHEIC Exploratory Ohm “Decay” Detection: Healthy wood typically has higher resistance (around 400 to 500 kΩ), whereas decaying wood shows a significant drop in resistance (often below 50 kΩ) because damaged cells release metal ions that conduct electricity better.
ENDORHEIC Tree Sample Ohm “Decay” Detection: Healthy wood typically has higher resistance (around 400 to 500 kΩ), whereas decaying wood shows a significant drop in resistance (often below 50 kΩ) because damaged cells release metal ions that conduct electricity better.

Arterio Vascular “Vitality”: Low resistance readings can also indicate healthy but very dry wood, requiring arborists to cross-reference with other signs.
Dryness (Moisture Content):
ENDORHEIC Electrical Conductivity: Moisture meters estimate the water content of wood by measuring changes in dielectric constant or power loss.
