Non-destructive Plating Thickness Gauge

Non-destructive coating thickness gauges operate based on the principles of magnetic induction or eddy currents. The probe, when in contact with the coating, generates changes in the electromagnetic field, and the thickness is calculated by measuring the signal differences between the substrate and the coating. These gauges are used for on-site rapid detection of non-conductive coatings on metal substrates or insulating coatings on non-ferrous substrates, making them suitable for coating quality control in industries such as automotive and electronics.
Selection
When selecting, consider matching the substrate type with magnetic induction or eddy current technology, clarify the measurement range and accuracy requirements, and check the instrument calibration certificate and probe adaptability. Pay attention to the temperature and humidity conditions of the operating environment, ensure the instrument's protection level meets on-site needs, trial-test for repeatability, and evaluate whether the data storage function meets recording requirements.

Application of Coating Thickness Gauges in Electroplating Thickness Detection
Coating thickness gauges are used to measure the thickness of electroplated layers, primarily employing the electromagnetic induction method for measuring non-magnetic coatings on magnetic substrates, or the eddy current method for measuring insulating coatings on non-magnetic metal substrates.
Eddy current thickness gauge measures metal coatings on non-conductive substrates.
The eddy current thickness gauge utilizes the principle of electromagnetic induction, generating an alternating magnetic field through the probe coil to induce eddy currents in the metal coating, thereby measuring thickness based on changes in coil impedance.
Coulometric Method Coating Thickness Gauge for Non-Destructive Measurement of Precious Metal Coatings
The coulometric coating thickness gauge measures the thickness by calculating the amount of electricity required to dissolve the precious metal coating through the principle of electrolytic dissolution. This method is non-destructive to the overall sample, only forming tiny electrolytic spots.
Application of Electrolytic Thickness Tester in Quality Control of Precision Electroplating Layers
The electrolytic thickness gauge measures coating thickness through the principle of electrochemical dissolution, calculating based on Faraday's law, offering high accuracy and independence from calibration.
Selection of Coating Thickness Measurement Methods: Coulometry vs. Dissolution in Electrolytic Thickness Gauges.
This article compares two techniques in electrolytic thickness gauges: the coulometric method and the dissolution method. The coulometric method measures coating thickness through electrochemical dissolution, making it suitable for single-layer metal coatings with simple operation and high accuracy. The dissolution method, on the other hand, measures thickness via chemical dissolution, making it more appropriate for multilayer or complex coatings.
