Two types of thickness gauges, digital thickness gauges and A-Scan (Amplitude Scan) thickness gauges. While they both serve the same purpose, their functionalities differ.

A-Scan Thickness Gauges: |
| Function: Digital gauges are the workhorses of thickness measurement. They use ultrasonic waves to penetrate the material and calculate the thickness based on the time it takes for the sound wave to bounce back. |
Function: Similar to digital gauges, A-scan gauges utilize ultrasonic waves for measurement. However, they offer a more advanced feature: the A-scan display. |
| Display: These gauges provide a direct digital readout of the thickness on a screen, making them user-friendly and ideal for quick and repetitive measurements. |
A-Scan Display: An A-scan presents a graphical representation of the ultrasonic signal. By analyzing this waveform, users can gain insights into the material's condition. |
| Benefits: Easy to operate, portable, and cost-effective, digital gauges are perfect for basic thickness measurements in quality control applications. |
Benefits: The A-scan display empowers users to identify potential issues like corrosion or internal defects. This advanced functionality makes A-scan gauges valuable for inspections and complex measurements. |
Corrosion is a naturally occurring phenomenon typically characterised as the deterioration and degradation of a substance, usually a metal, due to environmental factors. Which if left unchecked can cause expensive and dangerous damage to all sorts of systems, from the pipelines and pressure vessels used in the utility sector to the structures and vehicles used everywhere else.
