IML Resistograph

The IML Resistograph is an instrument used for detecting and measuring cracks, voids, cavities and decay inside a tree. The small drilling needle extends as it penetrates the wood, measuring the resistance of the wood to reveal the relative density distribution. The density measurements, at a scale of 1:1, are recorded on waterproof wax paper strips or stored in an electronic unit to be downloaded with the integrated wireless Bluetooth adapter. The device can be used for tree care inspection, utility pole inspection, playground inspection, termite inspection, bridge inspection, and building inspection, anything where wood has been incorporated. Their web site offers useful information on available brochures (in multiple languages), downloadable videos and manuals, upcoming events and seminars, customer servce, a glossary, and photo gallery.

Trephor tool for extracting microcores

Trephor is a tool specifically designed for extracting small cylindrical wood fragments named microcores (15 mm in length and 2 mm in diameter) from living trees. The microcores contain the outmost stem tissues (bark, phloem, cambial zone) and the most recently formed tree rings. The tool was designed and tested by Sergio Rossi of the Department of Land and Agro-Forestry Systems at the University of Padova in Italy. An article about this tool can (soon) be found in the IAWA Journal. For more information, contact:

Sibtec Digital microProbe

"The Sibtec DmP provides reliable non-destructive detection and analysis of decay in all types of wood. The DmP is a lightweight, battery powered portable tool that uses a 1mm diameter probe to penetrate timber up to 1 meter deep. The tool measures the resistance to penetration of the probe and downloads the resulting data in digital form for analysis. Supplied with the microProbe is the 'Drill Control Centre' software for Win 95/2000 which provides a quick graphical view and transfers the raw data into Microsoft Excel®. Leaving a virtually undetected test hole the DmP is powered by a rechargeable battery pack which can provide up to 100 tests, making it ideal for field work."

Resistograph

The Resistograph is a micro-drilling device created by Frank Rinn in Heidelberg, Germany. As the microdrill enters into the sample, the resistance of the wood will change the rotation speed of the drill bit. These changes mark changes in the density of the wood, and can therefore be used to obtain ring width information without coring or sawing into the sample. The device can also be used to determine the amount of decay in living trees, dead stems, roof beams, bridge timbers, wooden frame houses, and streetside poles. It comes with a rechargeable battery pack, built-in printer and computer memory, and software. The drill comes in three sizes from 1 mm to 1/25 mm. For more information, contact:

Wood Decay Detection Drill

This product was created by Allied Associates Geophysical Limited in the United Kingdom, and the company also has sales offices in Germany and Belgium. The device is hand-held and lightweight, and capable of drilling all types of wood. All data generated by the drilling device is automatically digitized, and rapidly provides an accurate cross-section of the wood structure. Their brochure states that the drilling device can analyze "density, patterns of decay, and dendrochronology." The device also is useful for sampling of archaeological timbers non-destructively, and is most often used to detect decay in transmission poles and structural timber. Write or call them at:
