Wall Thickness Tester: Applications & Considerations

A wall thickness tester takes advantage of the materials’ properties and ultrasonic waves. It’s a popular Non-Destructive Testing (NDT) method that is used for testing metals, glass, ceramics, plastics and other types of materials.

Specifically, wall thickness testing using ultrasonic waves is useful in many industries such as:

  • Chemicals.
  • Food.
  • Oil and gas.
  • Machine building.
  • Ship building and repair.

Due to its importance and non-destructive nature, wall thickness testing is a vital part in quality assurance in many industries. That’s why many ultrasonic testing devices have been already developed to address the need.


One huge benefit of ultrasonic testing is that it’s low cost. The investment required is not that large compared to other testing methods. In addition, you can find many devices now that are economically priced while still being reliable.

Long and Reliable Operating Time:

The battery should last more than enough especially when it comes to field work or off-site inspection. For instance, the A1207 Ultrasonic Wall Thickness Gauge has a long battery life (up to 24 hours when full charged).

When you are browsing through wall thickness testers and your application requires field work, one of the first things you should consider is the battery life.

Saving of data:

Human errors can still be common even in sensitive industrial applications. Many engineers and technicians now often rely more on recorded data when assessing problems and situations (and for double checking as well).

That’s why some choose a wall thickness gauge with a built-in data logger. For example, the Elektrophysik Minitest 400 Series UT Gauges have a built-in data logger, which allows for the saving and evaluation of measured values.

Wall thickness tester specific for your application:

There are wall thickness gauges for testing both hard materials and hollow bodies. There are different instruments which are ideal for specific applications.
