Dial-Type Thickness Meter

The dial thickness gauge measures thickness through mechanical contact, where the probe touches the material surface and internal gear transmission drives the dial pointer to display the thickness value. It is used for quickly measuring the thickness of coatings or substrates of materials such as paints and plastics in the laboratory. Its simple operation makes it suitable for on-site sampling inspections.
Selection
When selecting, consider that the measurement range should cover the sample thickness, and the accuracy should meet the testing requirements. For dial indicators, ensure that the scale divisions are clearly legible. Choose probe materials such as quenched steel or tungsten carbide based on the hardness of the object being measured. The clamping force should be adjusted to avoid deformation in soft materials. Regularly calibrate the instrument using standard calibration blocks to ensure accuracy.
