UM5 Gen3 Corrosion Thickness Gauge

Product Model: UM5D Gen3 (Standard Dual-Crystal Version)
UM5 Gen3 (Monocrystalline and Polycrystalline Integrated)
UM5T Gen3 (High-Temperature Version)
Application scope: thickness measurement for pipeline corrosion, high‑temperature boilers, materials with high attenuation, and penetration of thick anti‑corrosion coatings, among other thickness‑measurement scenarios.
Product Overview: The UM5Gen3 thickness gauge is engineered to tackle a wide range of thickness‑measurement challenges, making thickness measurement simpler than ever. Since its launch in 2011, it has benefited from 15 years of technological refinement and has now evolved into its third generation, serving as the core flagship product of Yushi Pioneer. Its key strength lies in its robust manual and automatic measurement capabilities. With an optional high‑temperature probe, it can effortlessly perform thickness measurements at temperatures up to 500°C. Designed to meet IP67 dust‑ and water‑resistance standards, its rugged body and rubber protective cover, combined with a hands‑free bracket and neck strap, ensure reliable performance even under the most demanding industrial inspection conditions.

Standard Configuration

Manual mode solves a wide range of measurement challenges.

· Equipped with comprehensive waveform adjustment capabilities
　Gain, mute, gate, polarity, type, and multiplier—any echo can be locked, all while benefiting from the hardware’s exceptional signal-to-noise ratio and sensitivity.
· Solving various measurement challenges
　Measures pitting corrosion, corrosion pits, highly attenuative materials, multilayer composite panels, and more.
· Thickness measurement through thick coatings
Use a 2.25 MHz probe to perform high-precision measurements on 300 mm-thick plastic material, or to penetrate it.
Measure the thickness of metal substrates coated with a 200 mm-thick plastic layer.
No manual adjustment required; intelligent adaptive measurement.

· Automatic mode
　Building on a robust technical foundation rooted in manual mode, automated measurements are seamlessly enabled and fully leveraged. Single‑crystal probes can penetrate coatings up to 30 mm thick, while dual‑crystal probes can handle coatings up to 5 mm thick—without any manual parameter adjustments—offering simple, efficient operation suitable for most routine measurement applications.
Key Technical Challenges and Solutions in High-Temperature Thickness Measurement

· The coupling agent evaporates and dries instantaneously, leaving an extremely short measurement window.
　Employing high-speed measurement, automatic freeze‑frame, and directional capture technologies, it achieves millisecond‑level rapid measurement and precise echo acquisition.
· High temperatures cause probe performance degradation, resulting in significant temperature drift.
　By employing an echo‑to‑echo measurement mode, temperature drift is eliminated in principle, achieving true zero temperature drift for the probe.
· The sound velocity of the material under test varies with temperature, leading to increased measurement error.
　Built-in professional temperature-compensation software that dynamically corrects sound-speed deviations at elevated temperatures.
· Harsh high-temperature field environment
　Equipped with a full suite of auxiliary accessories: couplant dispenser, 4-inch/6-inch extension handles, armored cable, and a four-point neck strap.
Powerful application features

· Numerical Interface
　The large, color-coded digits are easy to read at a glance, with minimum/maximum values and the difference/reduction rate toggled for display.
· A-scan interface
　Real-time waveform display is used for measurement verification, and waveform-based debugging can help ensure accurate thickness measurements under complex operating conditions.
· B-scan interface
　Single‑value B‑scan is well suited for corrosion inspection. Based on thickness readings and probe position, it displays a side‑view profile of the test material, providing an intuitive visualization of thickness distribution and corrosion morphology in the inspected area, thereby helping inspectors quickly identify defects such as localized thinning and pitting.
