Product Features & Applications

Product Features:

  • Support A – Scan Waveform Thickness Measurement.
  • Ergonomically optimized design, compact structure, ultra – small size, easy to carry, and comfortable to hold.
  • Precise thickness measurement, capable of penetrating coatings. No couplant is required,
  • and there is no need to polish the workpiece surface. The presence of paint, cladding, unevenness, etc. on the surface to be inspected is allowed.
  • The instrument has multiple material sound velocities pre – stored intemally. Meanwhile, material sound velocities can be dynamically added and deleted. The sound velocity calibration is equipped with a temperature compensation function to improve measurement accuracy.
  • High – definition LCD black – and – white screen display, suitable for measurement environments under various lighting conditions.

Product Applications:

  • Petrochemical industry: High-temperature pipeline inspection, non-contact thickness measurement without couplant, suitable for 800C high-temperature working conditions and coated pipe walls.
  • Shipbuilding: Thickness detection of hull steel plates, no polishing for rough surfaces, fast batch measurement of large-area plates.
  • Power industry: Thickness measurement of boilers and pressure vessels, stable measurement in high-temperature environments to ensure safe operation of pressure equipment.
  • Rail transit: Inspection of steel rails and vehicle metal parts,portable all-in-one design for fast and accurate on-site thickness data acquisition.
  • Machinery manufacturing: Thickness measurement of castings and forgings, compatible with various metal materials, meeting measurement needs of both thin parts and thick plates.
  • Steel structure construction: Thickness verification of building components, non-contact measurement without damaging workpieces, improving inspection efficiency.
