Nondestructive testing of glulam beam using an IML Resistograph
Testing and Microscopy
Wood Science Consulting has over 25 years of experience in the use of a Resistograph (i.e. resistance drill) to conduct non-destructive testing of wood elements in service and facilitating any clients that are seeking mechanical testing.
Resistance Drilling (Nondestructive testing)
For non-destructive testing of lumber, timbers, glulam beams and arches, piles and poles, Wood Science Consulting uses a Resistograph, or resistance drill, which is a very effective nondestructive tool for assessing the condition of wooden timbers. The PD Series, is equipped with computer software, excellent graphical imaging, and increased efficiency in drilling time. Common structures inspected include; old mill buildings, covered bridges, historical structures, utility poles, marine pilings and foundation pilings.

Light and Stereo Microscopy
Wood Science Consulting has an Olympus light microscope with magnification up to 400X which is used for wood species identifications and wood decay or microbiological analyses. Photomicrographs are recorded digitally for high quality graphics and are annotated as needed for reporting. Additionally, WSC utilizes a stereo microscope for close examination of products not requiring high level magnification such as finishes and coatings.
