InterNACHI members test out a new inspection technology.

Pictured above are InterNACHI members Kent Shepard of the Peak to Prairie Inspection Service and InterNACHI janitor Nick Gromicko testing out a resistagraph and viewing one of the recordings. The resistograph is one of the few tools designed for low invasive detection of hidden wood decay.  It does this by measuring the resistance met by a 1/8" drill bit and recording the results on a wax paper strip (shown) or in a electronic reader also available for transferring results to a computer, where the graph image can be manipulated for closer examination, or e-mailed.  By means of sophisticated mechanical and electronic sensors, variations in torque are translated into a graphical output which depicts the internal conditions encountered by the drill.
