Boring way to test quality of timber

QUALITY of structural and felled timber can be monitored using Fujikura Europes portable Resistograph F-series instrument.

Using a portable, rechargeable electric drill as its power source, the unit drives a small-bore needle into the timber.

The amount of resistance required to bore into the timber is recorded on a wax paper strip, to provide an instant assessment of timber quality.

At a weight of 2.5kg, the Resistograph F costs about £2000. (01373-825582).
