The Hammer Electrode penetrates through structural materials like sub floors and framing to a depth of 1.38" (35 mm). 
The insulated pins determine the exact moisture content of wood or the Wood Moisture Equivalent (WME) percentage of other materials. 
Use it to evaluate the extent of water damage during an inspection and while monitoring the drying process.
