Metal Thickness Meter

Metal thickness gauges measure the thickness of coatings or materials on metal substrates using ultrasonic, eddy current, or magnetic principles. Ultrasonic gauges calculate thickness based on the reflection time of sound waves, eddy current gauges detect non-magnetic coatings through electromagnetic induction, and magnetic gauges measure the thickness of non-magnetic layers on magnetic substrates based on changes in magnetic resistance. They are used for quality inspection, corrosion prevention evaluation, and production monitoring.
Selection
When selecting a metal thickness gauge, consider the substrate type (magnetic or non-magnetic), coating properties, measurement range, and accuracy. Choose between portable or fixed models based on the on-site environment, and determine whether data storage functionality is required. Verify the instrument’s applicability by referring to industry standards, and compare the measurement limits of instruments based on different principles.

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.
Comparison of Dual-Principle Instruments: Magnetic Induction vs. Eddy Current for Coating Thickness Measurement
This article compares the principles of two coating thickness gauges. The choice of method depends on the substrate material: magnetic induction is used for magnetic metals, while eddy current is applied for non-magnetic metals.
Eddy current thickness gauge detects coatings on non-ferrous metals.
The eddy current thickness gauge operates on the principle of electromagnetic induction, generating an alternating magnetic field through the probe coil, which induces eddy currents on the surface of non-ferrous metal substrates.
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.
