123W The ideal Training School Flaw Detector

The 123W is a simple to operate flaw detector and is used by the world’s leading training organisations. With the user interface becoming familiar in minutes technicians can concentrate on operation and learning ultrasonic
theory. The “analogue feel” from the high quality broadband amplifier shows all the detail required to demonstrate how ultrasound changes with defect types, such as holes and cracks, essential in understanding ultrasonic's
at Level I and II. For classroom presentation the 123W has a composite video output for connection to LCD projectors.

Advanced Defect Sizing Tools as Standard

Weld and pipe inspection are major applications for the Sitescan series and we have therefore equipped them with the latest software tools for defect sizing. The 123W has DAC sizing techniques. The use of integrated sizing software reduces analysis time and hence speeds inspection.

Multiple standard sizing techniques are essential for service companies working to different customer standards, especially as service work becomes more international and operators are required to work to different codes.

High Visibility Display

For any flaw detector the display is a crucial element. The Sitescan has a colour transflective TFT display as standard, providing high visibility at any light level. The choice of colours for menus and waveform display enhance clarity, with the LCD simulation mode giving direct sunlight readability. The TFT does not suffer the typical black out problems or temperature limitations of LCD giving full weather capability. The new Full Screen mode maximizes the A-scan area to improve readability further whilst testing and its fast response and peak capture functionality ensure any indication is clearly displayed, even if it only appears for one cycle of the PRF.

High Performance with Total Control

The Sitescan delivers high performance and advanced features, yet our engineer's experience in user interface design has ensured it's easy and quick to use. The acknowledged ease of use of previous generation Sitescans has been enhanced with the menu navigation key, providing easy access to functions. The menu structure has been designed to guide the user through their task with operation
quickly becoming second nature.

Sonatest's reputation for robust design and proven reliability is an important aspect of flaw detector ownership. Down time is expensive and should be minimized to ensure maximum productivity. The Sitescan series is constructed to high standards using Xenoy plastics and sealed to IP67, giving excellent water resistance so it can withstand the tough environments in which operators work. The Sitescan comes with 2 years warranty, extendable to 5 years with Sonacover, supported by a worldwide service network.
