The ultrasonic thickness gauge is designed using the pulse-reflection ultrasonic measurement principle. It is used for professionally measuring coating thickness on non-metallic surfaces such as plastic parts, wood, and glass, as well as the substrate thickness itself. It can also measure coating thickness on metal surfaces and the thickness of the metal substrate.

Ultrasonic Thickness Gauge
The ultrasonic thickness gauge is designed using the pulse-reflection ultrasonic measurement principle. It is used for professionally measuring coating thickness on non-metallic surfaces such as plastic parts, wood, and glass, as well as the substrate thickness itself. It can also measure coating thickness on metal surfaces and the thickness of the metal substrate.
Micron-level accuracy and industrial-grade precision
Equipped with a high-speed ADC for rapid data acquisition, the thickness gauge offers resolution down to 1μm. It provides superior accuracy in micron-level thickness measurements, making it an ideal solution for demanding industrial inspection tasks.

Multi-Layer Thickness Measurement Support
Measures coating thickness on virtually any substrate; supports measurement of up to 3 layers of coating or coating + substrate for complex inspections


Continuous Measurement Mode
The device has a continuous measurement mode to increase efficiency and accuracy in thickness measurement.


High Resolution IPS
Color Display
Industrial-grade IPS display provides clear and vivid thickness measurement values that are easy to see even in complex lighting conditions
Zero Point Calibration Calibration
Since the probe can be zeroed before measurement, the thickness gauge provides accurate coating thickness readings and maintains high precision and stability in measurement data.
