Ultrasonic Thickness Gauges for Accurate Non-Destructive Testing

Durable and highly precise thickness gauges designed to measure material integrity without surface damage or downtime

Overview

Ultrasonic thickness gauges are essential tools for non-destructive material inspection, used to accurately measure the internal thickness of metals, plastics, composites, ceramics, and other materials without requiring access to both sides. These tools are indispensable in quality assurance, structural integrity assessment, and corrosion monitoring in both industrial and field environments. Capable of detecting material loss and identifying defects invisible to the eye, ultrasonic thickness gauges improve safety, reduce downtime, and ensure compliance with regulatory standards.
This page offers a complete overview of ultrasonic thickness measurement technology, from core features and applications to compatibility and real-world case studies. Acoustic Testing Pro delivers high-performance solutions for businesses across North America, backed by deep industry expertise and rigorous product development. As a growing B2B leader, we support customers through product innovation, responsive technical support, and reliable, field-tested equipment designed to meet the demands of modern inspection workflows.

Case Studies

United States

Pipeline Integrity Assessment – Energy Sector, Midland, TX

An energy provider deployed GAO Tek ultrasonic thickness gauges to perform spot checks on aging transmission pipelines. The portable devices helped locate corrosion-prone areas, reducing inspection time by 40% and ensuring regulatory compliance.

United States

Aircraft Component Evaluation – Aerospace Maintenance Hub, Wichita, KS

Technicians used precision ultrasonic gauges to inspect fuselage and wing spars for internal thinning. The high-resolution measurements ensured airworthiness and extended component life cycles, while minimizing aircraft downtime.

Canada

Water Tank Inspection – Municipal Infrastructure, Calgary

City engineers incorporated Acoustic Testing Pro’s wireless ultrasonic tags to continuously monitor steel tank wall thickness. Real-time data alerts helped the team prioritize preventive maintenance, extending asset service life and reducing emergency repairs.
