Hollow Wood Thickness Gauge

The hollow wood thickness gauge uses ultrasonic or electromagnetic waves to penetrate the interior of the wood and detect the thickness of hollow structures. It is used to measure the wall thickness of hollow materials such as wooden boards and artificial boards, and to determine the structural integrity of materials in wood product production and quality inspection.
Selection
When selecting, consider that the measurement range should cover common wood thicknesses, the accuracy should meet process requirements, and the probe size should be compatible with the detection surface. Pay attention to the instrument's adaptability to wood types and humidity levels, ensuring ease of operation and data output methods align with on-site needs.
