DeFelsko PosiTector UTG C Ultrasonic Thickness Gauge

DeFelsko’s PosiTector UTG C Ultrasonic Thickness Gauge measures the wall thickness of steel, plastic, etc.


DeFelsko PosiTector UTG C Ultrasonic Thickness Probe measures material thickness through paint, linings, and coatings, without having to remove the coating. Also ideal for measuring on sandblasted materials or other applications where a durable wear-face is required.

DeFelsko’s New Standard Gauge Body features storage of 1,000 readings per probe. DeFelsko’s New Advanced Gauge Body features storage of 250,000 readings from multiple probes in up to 1,000 batches and sub-batches.


  • 5 MHz dual element probe with wear-resistant Alumina probe tip
  • Automatically disregards the coating when measuring wall thickness, eliminating the need to remove and repair paint in order to evaluate the surface
  • Resolution of 0.001″ (0.01 mm)
  • Accuracy to ±0.001″ (±0.03 mm)
  • Single echo measuring range 0.040″ to 5.000″ (1.00 to 125.00 mm)*
  • Large, easy-to-read, graphics LCD with multilingual support
  • Hi contrast color display with back-light
  • One-handed menu navigation
  • Pre-programmed Velocities – simply select from a list of common materials or enter your own with ease
  • Measures up to 5 inches on uncoated carbon steel
  • Bi-color indicator light – ideal in a noisy environment
  • RESET feature instantly restores factory settings
  • Solvent, acid, oil, water and dust resistant-meets or exceeds IP5X
  • Scratch/Solvent resistant display suitable for harsh environments
  • Shock-absorbing protective rubber holster with belt clip
  • Precision transducers provide fast, accurate readings
  • Hi-RES mode increases displayed resolution for use on applications that require greater precision to NIST included with every gauge
