General Info

Ultrasonic thickness gauge with A-scan UT-2A is a powerful, lightweight and portable thickness gauge, made in an ergonomic shock-resistant case with rubber protectors – a modern industrial version of a general-purpose thickness gauge. It is an excellent choice for expert ultrasonic testing in the laboratory and the field conditions.

Unlike conventional thickness gauges, which show only one digit, the A-scan thickness gauge allows visualization of the signal for subsequent analysis by the operator. As a rule, such an opportunity is needed by professional users, but even for a beginner it will be an extremely useful feature. By visually observing the reflected signals on the screen of the device, it is possible to exclude false alarms, to set the thickness gauge as accurately and correctly as possible. Working with a A-scan, it is possible not only significantly increase the accuracy of measuring the thickness, but, among other things, carry out defect detection of products. That is, in fact, such a thickness gauge will already solve flaw detection tasks that are performed using an ultrasonic flaw detector.

Thanks to the method of thickness measurement by signal crossing through zero implemented in the UT-2A ultrasonic thickness gauge, the maximum measurement accuracy available for ultrasonic thickness gauges is achieved. This measurement method is independent of the signal gain settings, as opposed to the edge measurement method.

The main advantages:


Due to implemented in Ultrasonic Thickness Gauge UT-2A zero-crossing method of thickness measurement have achieving maximum of measurement accuracy from ever produced Ultrasonic thickness gauge. That method of measurement doesn`t depend on gain of signal in contradistinction to method of edge measurement. Because of applying high-performance, computing FPGA microcircuit it turned out to realize high resolution in thickness, while maintaining the speed of operation and the stability of the signal


That type of device would be appropriate even for unskilled user with using of digital measurement mode, the same as at initial devices. The digital values of thickness are displayed as large font on the screen and needless to adjustment by A-scan. Therefor simplicity and convenience identical to classical Ultrasonic Thickness Gauge UT-1M.


Ultrasonic thickness gauge have useful and especial operation modes for increase convenience of use.

  • Control mode. User can set up nominal thickness and permissible deviation thru nominal value. During testing Ultrasonic Thickness Gauge UT-2A would indicate (thru lights or sound) if measured value deviate above limits. That is makes simplicity in testing operation and decreases ability to making mistakes.
  • Product profile display mode (B-Scan). On the screen would displayed product profile by probe scanning surface. That mode is making able to visualize profile (section) of tested object. This mode can be used when it is necessary to present a report with illustrations of the object flaws.


For professional users, the device implements manual modes of thickness measurement by all major methods:

  • ECHO
  • ECHO with adjustable gate (place of measurement)
  • ECHO-ECHO (DUAL ECHO) – usually used when measuring thickness through a coating. The method allows user to measure the thickness of the metal under the coating, without polishing.
  • PEAK-PEAK – the method is similar to ECHO-ECHO with the difference that the trigger moment is calculated not by the crossing of zero, but by the maximum of the signals in the gate.

The use of a large number of measurement methods allows users to flexibly use the ultrasonic thickness gauge, depending on the specific task.


Unlike conventional thickness gauges, which show only one thickness value, the A-scan thickness gauge allows visualization of the signal for subsequent analysis by the operator.

As a rule, function of A-scan is needed for professional users but even for beginner it would be useful function. Making observation at display visualization of reflected signals it`s able to eliminated false triggering, adjust the thickness gauges as correctly and accurately as possible. By working with a signal is able not only significantly increase the accuracy of thickness measurement and in that case to carry out flaw detection of products, in essence Ultrasonic Thickness Gauge UT-2A are able to solve flaw detection main tasks.
