Non-metallic Ultrasonic Thickness Gauge

Non-metallic ultrasonic thickness gauges emit ultrasonic waves into materials through a probe, receive echoes, calculate the propagation time, and convert it into thickness based on the speed of sound. They are used to measure the thickness of non-metallic materials such as plastics and ceramics, monitoring material uniformity in manufacturing and quality inspection.
Selection
When selecting a non-metallic ultrasonic thickness gauge, it is essential to consider matching the probe frequency with the material's acoustic properties, ensuring the measurement range covers the target thickness, meeting the required precision for the application, ensuring ease of operation suits the working environment, and referencing brand reliability and calibration services.
