Portable Ultrasonic Thickness Tester

Portable ultrasonic thickness gauges operate on the principle of ultrasonic wave propagation and reflection in materials, calculating thickness by measuring the round-trip time of the sound waves. They are used for rapid, non-destructive testing of wall thickness in materials such as metals and plastics, commonly applied in on-site inspections of industrial equipment like pipelines and containers.
Selection
When selecting a portable ultrasonic thickness gauge, it is essential to consider the measurement range, accuracy, material compatibility, probe frequency, and calibration capabilities. Based on practical application scenarios, such as the material being measured, surface conditions, and environmental factors, choose a model that is easy to operate and offers suitable battery life.

Ultrasonic Thickness Gauge Selection: Technical Considerations for Probe Configuration and Measurement Modes
This article primarily introduces the technical factors to consider when selecting an ultrasonic thickness gauge. In terms of probe configuration, the frequency affects both resolution and penetration depth, while crystal size determines adaptability to curvature and surface conditions. Dual-element probes offer a smaller dead zone compared to single-element probes, and delay-line probes are suitable for thin-wall and high-temperature applications.
Ultrasonic thickness gauge for detecting thick coatings and composite coatings.
Ultrasonic thickness gauges measure coating thickness using the principle of ultrasonic pulse reflection, calculating the result based on the propagation time of sound waves in the material and the speed of sound. When detecting thick coatings and composite coatings, challenges such as acoustic attenuation of the material, unknown sound speed, and signal recognition at multi-layer interfaces must be addressed.
