Different Methods of Thickness Testing 
  • Calipers: Traditional mechanical calipers provide a quick and simple way to measure thickness, but they may not be suitable for hard-to-reach or coated surfaces. 
  • Micrometers: Micrometers offer higher precision than calipers, but they are also limited in their accessibility. 
  • Eddy Current Testing: This electromagnetic method is ideal for conducting non-destructive thickness tests on conductive materials. 
  • X-ray Radiography: X-ray radiography can provide valuable insights into material thickness but may involve hazardous radiation exposure. 
  • Ultrasonic Thickness Testing: Ultrasonic testing uses high-frequency sound waves to measure thickness non-destructively, making it one of the most versatile and widely adopted methods.
