Ultrasonic Thickness Gauge is designed for rapid non-destructive thickness testing of:

products made of various metals, alloys and other materials;

glass, plastic, composite and other products from non-metallic materials;

the walls of the tanks, pipes, casing parts, sheets, overhead, and other structures, including the corroded surfaces, pitted, with scum, etc.;

products during their production and operation;

metal products for diagnostic and expert work with one-side access to the tested object.


Ultrasonic method for measuring thickness

The device complies with ASTM E797 Standard Practice for Measuring Thickness by Manual Ultrasonic Pulse-Echo Contact Method.

Ultrasonic Thickness Gauge operates on the principle of measuring the propagation time of ultrasound in the given material. The pulse generator produces a high frequency electrical pulses that excite the piezoelectric transducer (Probe). The transducer converts electrical signals into the elastic (mechanical) vibrations – sound waves. These waves propagate from the surface of the input to the reflective (bottom)  surface and back, re-taken and converted into electrical signal by means of PET. After that device calculates the thickness of tested object.


It has Echo-Echo mode. Using special Echo-Echo probe, it allows to measure thickness of metals, through paint coatings (up to 1mm).
