Non-metal material thickness Gauge

Non-metallic material thickness gauges utilize ultrasonic or electromagnetic waves to penetrate materials, measuring the time difference or intensity changes of reflected or transmitted signals to calculate thickness. They are used to detect the thickness of non-metallic materials such as plastics, coatings, and rubber, ensuring production meets specification requirements.
Selection
When selecting a non-metallic material thickness gauge, consider the type of material being measured and its thickness range, and choose an instrument based on ultrasonic or electromagnetic principles. Pay attention to measurement accuracy, probe size, and calibration methods to ensure the instrument is suitable for the field environment and usage requirements.
