Needle Thickness Gauge

The needle-type thickness gauge measures the thickness by contacting the material surface with a probe and converting the probe displacement into a thickness reading. It is used for detecting the thickness of thin-layer materials such as coatings and plastics to ensure coating uniformity.
Selection
When selecting, consider that the measurement range covers the sample thickness, the probe pressure does not damage the material, and the accuracy meets the process requirements. Verify the instrument calibration certificate and ensure the operating interface aligns with usage habits.
