AELAB provides thickness measurement instruments for evaluating coatings, metal sections, surface profiles and wet-applied films in laboratory, production and field inspection environments.
The available category includes coating thickness gauges, ultrasonic thickness gauges, surface profile gauges and wet film combs. These instruments support non-destructive measurement, incoming-material inspection, corrosion monitoring, coating-process control and routine quality assurance.
AELAB thickness gauges can be selected according to the substrate material, coating type, expected thickness range, measurement principle, probe configuration and working environment.

What Is a Thickness Gauge?
A thickness gauge is a measuring instrument used to determine the thickness of a coating, film, material section or remaining wall without relying only on visual inspection. Depending on the model, measurement may be performed through magnetic induction, eddy-current technology, ultrasonic testing or direct mechanical comparison.
Thickness measurement helps manufacturers and inspectors verify coating uniformity, identify material loss, monitor corrosion and confirm that finished components meet internal quality requirements.
Typical Applications
Verification of paint, protective coating, plating, enamel and polymer-layer thickness.
Monitoring the remaining thickness of metal tanks, pipes, panels and structural components.
Evaluation of coated machinery, storage equipment, greenhouse structures and processing-system components.
Checking blasted-metal surface profiles before primers or protective coatings are applied.
Understanding the Main Measurement Principles
Magnetic-induction gauges are generally selected for measuring non-magnetic coatings over ferrous substrates. Common examples include paint or plastic coatings applied to steel and iron components.
Eddy-current instruments are generally used for non-conductive coatings on non-ferrous conductive substrates, including aluminum and other suitable metals.
Ultrasonic thickness gauges transmit sound waves through the material and calculate thickness from the travel time of the signal. This method is especially useful when only one side of a pipe, tank or structural component is accessible.
A wet-film comb is pressed into a freshly applied coating. The last wetted tooth and the next dry tooth provide an immediate estimate of the applied wet-film thickness.
How to Select the Right Thickness Gauge
The correct model should be selected according to the material being measured rather than only the expected thickness. The substrate, coating conductivity, surface condition, access to the test area and required measurement range all influence the final instrument choice.
| Selection Factor | Questions to Consider |
|---|---|
| Measurement Target | Do you need to measure a coating, a solid material section, remaining wall thickness, surface profile or wet film? |
| Substrate Material | Is the base material steel, iron, aluminum, copper, plastic, glass or another material? |
| Coating Type | Is the coating paint, enamel, plastic, plating, protective film or another surface layer? |
| Measurement Range | What are the minimum and maximum thickness values expected in the application? |
| Surface Geometry | Will measurements be performed on flat panels, curved pipes, narrow sections, corners or irregular components? |
| Probe Configuration | Is an integrated probe sufficient, or is a separate external probe required for difficult measurement points? |
| Material Access | Can both sides of the material be reached, or must thickness be measured from only one side? |
| Calibration Requirements | Are calibration foils, reference blocks, substrate correction or routine verification required? |
| Working Environment | Will the instrument be used in a controlled laboratory, production area, maintenance workshop or outdoor field environment? |
| Data Management | Are result storage, statistical calculation or transfer to a computer required? |

Recommended Thickness Measurement Workflow
| Step | Inspection Stage | Recommended Action |
|---|---|---|
| 1 | Identify the Material | Confirm the substrate, coating type and expected thickness range before selecting the measurement technology. |
| 2 | Inspect the Surface | Remove loose contamination and check whether curvature, roughness or corrosion may influence the result. |
| 3 | Verify the Instrument | Use suitable reference materials, calibration foils or blocks according to the instrument and test procedure. |
| 4 | Take Multiple Readings | Measure several representative points rather than relying on a single reading. |
| 5 | Review and Record | Compare the results with the project specification and document the location, average, minimum and maximum values where required. |

Frequently Asked Questions
What types of thickness gauges does AELAB supply?
AELAB offers coating thickness gauges, ultrasonic thickness gauges, surface profile gauges and wet film thickness combs for different inspection requirements.
What is the difference between magnetic and eddy-current measurement?
Magnetic-induction measurement is generally used for non-magnetic coatings on ferrous substrates, while eddy-current measurement is generally used for non-conductive coatings on suitable non-ferrous conductive substrates.
Can a coating thickness gauge measure metal wall thickness?
A coating gauge measures a surface coating over a substrate. Metal wall or material-section thickness normally requires an ultrasonic thickness gauge.
Why are several readings recommended?
Coatings and material sections may not be completely uniform. Multiple readings provide a more representative evaluation of average thickness and local variation.
What information should I provide for model selection?
Provide the substrate, coating or material type, expected thickness range, surface geometry, required accuracy, working environment and destination country.
Can AELAB recommend a thickness gauge for my application?
Yes. The AELAB technical sales team can review your measurement requirements and recommend suitable instrument types and available models.
Tell the AELAB technical team what material, coating or component you need to measure. Suitable models can be recommended according to the substrate, measurement range, surface geometry and required testing method.
The technical proposal can include available models, measurement principles, technical specifications, standard accessories, optional probes, delivery time, packaging and shipping information.
