Phosphating Film Thickness Meter

Phosphating film thickness gauges measure the thickness of phosphating layers on metal surfaces using magnetic induction or eddy current principles. The probe generates a magnetic field, and the phosphating film alters the magnetic circuit or eddy current response, allowing the instrument to calculate the thickness. This method is used to inspect the quality of phosphating treatment before coating application, ensuring corrosion resistance and coating adhesion.
Selection
When selecting a phosphating film thickness gauge, it is essential to confirm the substrate type: magnetic induction for ferrous substrates and eddy current for non-ferrous substrates. Consider the required thickness range and accuracy, and match the probe size to the shape of the workpiece being measured. Verify the instrument's calibration certificate and ease of operation to ensure compatibility with the production environment.
