Ultrasonic Thickness Gauges
Non-Destructive Wall-Thickness Measurement for Metals, Plastics & More
Ultrasonic thickness gauges provide a fast, reliable way to measure the remaining wall thickness of metal, plastic, and composite materials from one side only.
By sending high-frequency sound pulses through the material and timing the return echo, these instruments deliver highly accurate readings without cutting, drilling, or removing protective coatings.
Whether you’re inspecting ship hulls, monitoring pipelines for corrosion, or verifying the thickness of plastic tanks and structural components, ultrasonic technology ensures precise measurement and dependable data—even in harsh industrial environments.
Why Use Ultrasonic?
-
Non-Destructive & Efficient – Obtain accurate measurements without damaging the part or removing paint and coatings.
-
Corrosion & Erosion Detection – Identify hidden thinning early to prevent leaks, failures, or costly downtime.
-
One-Side Access – Perfect for tanks, pipes, or sealed structures where the opposite side is inaccessible.
-
Broad Material Compatibility – Works on a wide range of metals, plastics, and composites with appropriate probe selection.
-
Standards Compliance – Meets major international inspection standards used across marine, oil & gas, construction, and industrial sectors.
Typical Applications
-
Ship hull and ballast-tank inspection
-
Pipe and tube wall monitoring
-
Storage tank corrosion surveys
-
Chemical-processing equipment checks
-
Plastic or composite vessel verification
-
Structural steel thickness verification

The PosiTector UTG Family
DFT Instruments supplies the complete DeFelsko PosiTector UTG series, offering models and probes tailored to different applications:
- UTG C — Single-Echo (corrosion on steel)
Our most popular ultrasonic probe for general wall-loss/corrosion surveys on steel where coatings are thin/removed or you’re happy to measure in single-echo. - UTG M — Multi-Echo Through-Paint
Measures steel thickness through most coatings without removing paint (multi-echo/through-coating mode). - UTG P — Precision (thin materials)
High-frequency probe for thin metals and plastics, small-diameter tubing, and fine-gauge work. - UTG CLF — Low-Frequency (cast/attenuative)
Low-frequency probe specialised for cast metals and other attenuative/coarse-grained materials.
Each model features a large, impact-resistant colour touchscreen, rugged IP65-rated body, multiple measurement modes, and seamless data transfer via USB, Wi-Fi, or Bluetooth to PosiSoft software for professional reporting.
Ensure the integrity of critical assets with precise ultrasonic wall-thickness measurement. Contact DFT Instruments for expert advice on the right PosiTector UTG model and accessories.
