  • SOLID ONE with a really BIG SCREEN

Sonocon BL has an ergonomic shock-resistant ABS plastic case with additional rubber pads and is designed for use in field as well as in industrial conditions. The Sonocon BL has a 7.2” huge high-resolution display. In combination with well-designed interface, this enables observing the A-Scan without strain even distantly.

  • Versatile

Due to its case design and a 4-position folding handle, Sonocon BL can be comfortably placed on the table, pipe or another test object and even suspended. It also can be fixed on the inspector’s chest for better mobility.

  • Powerful and Multifunctional

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

  • Flaw detector,
  • A-Scan thickness gauge,
  • Corrosion monitor

This is realized with switchable software. In “UT” version Sonocon B grants all functions of a powerful ultrasonic flaw detection necessary for its setup, defect search and their advanced evaluation.

  • Usage in harsh environments

The instrument case carries an IP65 rating. The operation temperature ranges from –30°C to +50 °C (-22°F to 122°F). The flaw detector is resistant to ionizing radiation impact and is meant for operation under high humidity conditions.

  • Easy to use

Sonocon BL 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 performing fast and easy calibration with straight beam, angle beam and Rayleigh wave probes on standards or even a testing object.

To help new users to get used to its interface, Sonocon BL offers a number of options:

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