Zonotip for Low Ultrasonic Attenuation Measurement

Product Announcement from Proceq SA

Zonotip for Low Ultrasonic Attenuation Measurement-Image

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 0.8 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 â€" 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


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.
