Positector UTG, ultrasonic wall thickness gages
The Defelsko PosiTector UTG is an ultrasonic wall thickness gauge that measures thickness without removing paint, ideal for detecting corrosion in structures, pipes, and tanks.
The Defelsko PosiTector UTG ultrasonic wall thickness gauge is a non-destructive solution designed to measure material thickness without the need to remove coatings. It is ideal for inspecting painted structures, pipes, tanks, and industrial components exposed to corrosion, erosion, or wear.
Thanks to its advanced ultrasonic technology, it delivers fast, accurate, and reliable measurements, making it one of the most widely used Defelsko thickness gauges in industrial inspection and quality control.
How does the PosiTector UTG works?
The PosiTector UTG thickness gauge uses ultrasonic waves that travel through the material to the back wall, allowing calculation of the true material thickness without damaging the surface.
Multiple-echo models (UTG M) can measure metal thickness through paint without removing the coating.
It is ideal for measuring thickness on:
- Steel.
- Aluminum.
- Plastic.
- Cast iron.
- Pipes and tanks.
- Painted structures.
It complies with ASTM E797, ensuring professional accuracy and reliability.
Available PosiTector UTG Probe Types
Defelsko has developed different probes to adapt to each application:
1) UTG CA – Integrated Probe
- Based on the popular UTG C.
- Compact design, one-handed operation.
- Ideal for quick inspections.
2) UTG CLF – Low Frequency
- Designed for cast iron and highly attenuating materials.
- Dual-element 2.25 MHz transducer.
- Filters “grain noise” for improved accuracy.
3) UTG P – High Precision
- 15 MHz frequency.
- Ideal for thin materials: metals and plastics.
- Includes A-Scan function with dual cursors to measure distance between echoes (UTG M or UTG P probes only).
- Automatic probe tip temperature compensation.
