The Sonocon B belongs to the next generation of portable UT instruments. Using high-end electronics and having the richest set of modes and software features, it can solve any task that can be solved with a portable UT device.



  • Comfortable and Lightweight

The Sonocon B is a lightweight inspection system – only 0.95 kg (2 lbs). Due to its ergonomic shape and a hand strap, it can be quite comfortably operated with a single hand, which is particularly important in the field and especially at height. It can be used by both left- and right-handers. A high contrast display of optimal size and resolution (800×480) prevents the operator’s excessive eyestrain.

  • Powerful and Multifunctional

The Sonocon B is a digital UT tester combining 3 devices in 1:

  • a flaw detector,
  • an A-Scan thickness gauge,
  • a corrosion monitor

This is realized with the help of switchable software. In the “UT” version, the Sonocon B fulfils all functions of a powerful ultrasonic flaw detector necessary for its setup, defect search and their advanced evaluation. In the “Thickness gauge +” version it turns into an advanced A-Scan thickness gauge, which also can do corrosion mapping.

  • Usage in Harsh Environments

High contrast display allows working in direct sunlight. The operation temperature range is from –30°C to +50 °C (-22°F to 122°F). The flaw detector is resistant to ionizing radiation impact and is intended for operation in increased humidity conditions.

  • Easy-to-Use

The Sonocon B is highly user-friendly. Its interface philosophy can be stated as “Don’t browse menus, just push a button!”. All most frequently used functions are placed on its keyboard making them accessible in a single or a couple of button presses. This makes setup and evaluation procedures several times faster. A variety of built-in auto calibration procedures allow to perform fast and easy calibration with straight beam, angle beam and Rayleigh wave probes on standards or even test pieces.

To help new users get to know its interface, the Sonocon B offers a number of options:

  • Context backlight: In modes where a group of buttons is to be used, all relevant buttons are highlighted.
  • Menu item hints: All not trivial menu items show descriptions when activated (changed).
  • Menu presets: A user can choose one of 3 menu system presets:
    • Full: contains all menu items on 2 pages granting access to all UT instrument functions;
    • Simple1 & Simple 2: contain all basic functions on one page, grouped in a couple of menus. It is also possible to add any 3 or 4 extra menus from a Full Menu List.

Industrial applications:

Testing of equipment, e.g. of the lifting mechanisms.
Testing of metal works etc.
Testing of the mill rolls.
Equipment testing.
Selective acceptance testing etc.
