Pinhole Density Tester

The pinhole tester detects tiny pores in coatings or films by applying voltage. When current passes through a pinhole, it forms a conductive path, and the instrument records the location of the defect. It is used for quality inspection of materials such as paint and plastic films to ensure protective performance.
Selection
When selecting, consider the material's conductivity in relation to the test voltage range, and choose the electrode type based on the sample thickness. Environmental humidity affects accuracy and must be controlled. Compare the instrument's sensitivity with the requirements of the detection standards. The operation interface should be user-friendly, and regular calibration is necessary to account for electrode wear.
