An effective diagnostic tool for detecting wood degradation

BING® analyses the vibrations emitted by a piece of wood after impact, enabling rapid assessment of wood quality and potential degradation. The BING® system is portable and can be used outdoors. It is a valuable quality control tool throughout the entire life cycle of a wooden component. It also contributes to a sound hazard analysis and critical control point approach (HACCP).

BING®: a fast and portable wood diagnostic tool

Discover the system’s key advantages :

  • A diagnosis in less than 20 minutes;
  • Reliable results;
  • Suitable for all types of solid materials;
  • Compatible with different vibration sensors;
  • Dual power supply (mains or battery);
  • Portable, enabling in situ inspections across different locations;
  • Requires no laboratory equipment;
  • Offers potential for the development of customised applications.

BING®: a valuable tool for wood industry professionals and inspection or safety services

For wood processing industries

The system enables :

  • Grading of sawn timber;
  • Detection of manufacturing defects;
  • In situ inspection of roundwood or poles.

For internal or external services responsible for assessing the safety and integrity of infrastructure (public infrastructure, etc.)

BING® enhances your expertise in order to :

  • Reduce the risk of damage linked to structural failure of wooden components;
  • Ensure the replacement of defective parts before degradation worsens and leads to higher costs.

How can you benefit from the BING® system ?

The current system, combined with our expertise, enables the development of customised applications tailored to your specific needs.

Training modules are available on request, and our expert team can either provide maintenance services or train your staff in system maintenance.
