A1208 Ultrasonic Thickness Gauge

The Zonotip is designed to measure the thickness of ferrous and non-ferrous metals as well as parts made from polymers, glass, ice, and other materials with a low ultrasonic attenuation. The product’s measuring range on steel is from 0.7 to 300 mm. Two different probes are available: the standard dual-element 4.0 MHz transducer and the compact single-element 2.5 MHz transducer (only Zonotip+).The instrument can operate in three different modes (Norm, Memory, A-Scan), either displaying the current reading as digital numbers or as real-time graphical images (A-Scan – only Zonotip+). 


  • Solid body of light, shock-proof plastic
  • Suitable for difficult weather conditions (frost- and heat-proof)
  • Large high-contrast color display ensures visual control of the inspection process
  • Memory for 50’000 measurements
  • 4.0 MHz dual-element transducer
  • Automatic adaptation to the surface curvature and roughness
  • Automatic logging of max and min values while scanning the object
  • Measuring of the ultrasonic pulse velocity on a sample with known thickness
  • Color, sound and vibration indication when set limits are exceeded
  • USB connection to PC for data transfer
  • 8 different languages selectable
  • Metric and imperial units
  • Signal strength indication
  • Battery level indication and automatic switch off function.


Thickness measurements where only one-sided access is possible, such as

  • Pipelines
  • Tanks or pressure vessels
  • Erosion determination on pipes and tubes


The easy-to-use Zonolink Software, included in the package, offers data download and further analysis on a PC. Communication with the computer is provided through a USB port.
