Product Features & Applications
Product Features:
- Ergonomically optimized design, compact structure, ultra – small size, easy to carry, and comfortable to hold.
- High-precision thickness measurement, coating-penetrable, no couplant required, no need to polish workpiece surfaces; compatible with surfaces coated with paint, cladding, or with unevenness.
- Pre-stored sound velocities for various materials inside the instrument, supporting dynamic addition and deletion of material sound velocities; sound velocity calibration is equipped with temperature compensation 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.
