Non-metallic Plate Thickness Gauge

Non-metallic plate thickness gauges measure material thickness using ultrasonic or eddy current principles. Ultrasonic gauges calculate thickness based on the reflection time of sound waves, while eddy current gauges rely on electromagnetic induction. They are used to measure the thickness of non-metallic plates such as plastic, rubber, and glass, ensuring production meets specifications.
Selection
When selecting a non-metallic plate thickness gauge, consider the material type and thickness range to ensure instrument compatibility. Evaluate measurement accuracy and repeatability to meet practical needs. Check the operating environment, such as temperature effects. Refer to brand reliability and after-sales service to ensure long-term use.
