Overview

The new Sonatest RailScan 125+ flaw detector delivers a higher level of nearsurface resolution and penetrating power into a portable and rugged enclosure. It also offers more measuring capabilities than its predecessors for rail applications such as:

rail walking stick inspection solutions
rail manual defect sizing
rail bottom depth measurements

Features

Sonatest Ultrasonic Assurance of Quality

Based on 60 years of experience, the Railscan 125+ is powered by high-end software and electronic technologies:

Narrow Band amplifiers 2 MHz & 5 MHz
Up to 3 gates for complete inspection solutions
Encoder driven for Rail-Thickness auto-logging
Best signal-to-noise ratio on the market (SNR)

1) The Reference for Railway Companies

Approved by Network Rail, the owner and infrastructure manager of most of the rail network in England, Scotland and Wales, the Railscan 125+ takes part in the quality control procedures to ensure integrity assessment of the UK railway network.

2) High Visibility Display

For any flaw detector, the display is a crucial element. The Railscan 125+ has a colour transflective VGA display and maximum readability is achieved, even in direct sunlight conditions, through adjustable brightness and the choice of 9 colour palettes, including a black-on-white LCD emulation mode. The Full-Screen mode maximises the A-scan area to improve readability further whilst testing and its fast response and peak capture functionality ensure any indications clearly displayed, even if it only appears for one cycle of the 1 KHz PRF.

3) High Performance with Total Control

The acknowledged ease of use of the previous Railscan generation 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.

4) Robust & Reliable

Sonatest’s reputation for robust design and proven reliability is an important aspect of our flaw detector ownership. Downtime is expensive and should be minimised to ensure maximum productivity. The Railscan 125+ is constructed to high standards using a highdensity enclosure that is sealed to IP67, giving an excellent water resistance so it can withstand the railways’ harsh environments in which operators work. The Railscan 125+ comes with a 2 year warranty, extendable to 5 years with Sonacover, and a worldwide service network.

5) UT-Lity Data Management Software

UT-Lity software provides everything you need to manage your inspection data, configuration files and software updates.

Load, store, manage files both on the PC and on a connected flaw detector
Save, analyse, colour code and export thickness logging data to spreadsheets/asset management software
Update the Flaw Detector Firmware as and when updates become available on Sonatest website
