Non-contact Ultrasonic Thickness Gauge

Non-contact ultrasonic thickness gauges measure thickness by emitting high-frequency sound waves onto the material surface and calculating the time difference of the reflected waves. They are used for measuring high-temperature, corrosive, or coated surfaces to avoid contact damage. Commonly applied for monitoring the wall thickness of pipelines and containers.
