Small-diaMeter inner wall coating thickness Gauge

This instrument uses a probe inserted into the interior of the pipeline to detect differences in magnetic permeability or conductivity between the substrate and the coating, based on the principles of magnetic induction or eddy currents. It is used to measure the thickness of coatings on the inner walls of confined spaces such as pipelines and pipe fittings, ensuring corrosion protection or decorative effects. It is suitable for coating quality inspection in industries such as petrochemicals and water supply pipelines.
Selection
When selecting, consider matching the probe size to the minimum diameter and curvature of the pipeline. Choose between magnetic induction or eddy current principles based on the type of metal substrate. Check if the measurement range covers the expected coating thickness, and ensure the probe's wear resistance and the instrument's protection rating are suitable for the on-site environment.
