Portable Hand-Held Coating Thickness Gauge

The portable handheld thickness gauge operates on the principles of ultrasonic waves or electromagnetic induction. Its probe emits signals upon contact with the material surface and receives the echoes, calculating the time difference in signal propagation to determine thickness. It is commonly used for on-site rapid measurement of coatings, plates, and pipe walls, particularly in applications such as corrosion prevention in steel structures and quality inspection of plastic products.
Selection
When selecting, consider the type of material being tested: use eddy current principles for metals and ultrasound for non-metals. Choose the measurement range based on thickness, typically 0.1–200 mm. Pay attention to the curvature and surface roughness of the base material: use a small probe for curved surfaces and coupling agent for rough surfaces. Temperature compensation and automatic calibration functions are required.
