Ultrasonic Paint Film Thickness Meter

The ultrasonic paint film thickness gauge emits high-frequency sound waves through a probe towards the coating. The sound waves reflect at the interface between the coating and the substrate, and the instrument calculates the round-trip time difference of the sound waves to convert it into thickness. It is used to measure the thickness of paint and plastic coatings on substrates such as metal and plastic, and to verify coating quality in automotive repair and industrial painting applications.
Selection
Consider the type and curvature of the substrate when selecting: choose a universal type for metal substrates, and a specialized model for plastics. The measurement range should cover the expected thickness, with an accuracy of ±3% being sufficient. The probe size should match the shape of the measured object: use a standard probe for flat surfaces, and a miniature probe for small curved surfaces. The environmental temperature should be suitable for on-site conditions, and the device should come with a calibration certificate and basic functions.
