ArborSonic 3D Acoustic Tomograph

 Our most popular product among arborists

 Detects the size and location of decayed or hollow regions

 Works fast: a measurement can be completed in 5-10 minutes

 Creates a 3D model of the trunk with multiple layers of measurement

 Customizable wind load modeling is included in the software

 Utilizes non-destructive technique using sound waves (no radiation)

 For trees with thick bark, 12 cm long nails are also available

  1. Drive the transducers through the bark using a rubber hammer with even spacing around the trunk.
  2. Measure the distances between the transducers with a caliper and enter the measured data to the computer.
  3. Tap each transducer with a steel hammer to generate sound waves. ArborSonic 3D measures the travel times with microsecond precision to each transducer and transmits the data to the computer.
  4. The software calculates and displays the internal sound-velocity distribution of the tree.
  5. Measurements taken at various heights can be assembled into a 3D model.
