Non-Destructive Inspection Digital Ultrasonic Rail Flaw Detector Ultrasonic Rail Flaw Detector
9 independent flaw detection channels
Type A &B display
Probe self-test function
GPS positioning system
FD-GT-3 digital Ultrasonic rail flaw detector is the latest hand-pushed digital ultrasonic rail detection instrument. The instrument is equipped with global positioning system (GPS) and built-in storage device to record the whole process of flaw detection. The data can be easily imported into the computer through the SD card, so as to realize data management easily
Functional Features
- highlight 8.4 inch TFT screen, the sun visible;
- 9 + 1 channel configuration, anti-interference design, satisfy various demand on site inspection,
- preset type variety of rail flaw detection to set, and can be user-defined type rail flaw detection parameters;
- dynamic type A stored all the way, can store more than six months continuously testing data;
- fully sealed waterproof, dustproof design, adapt to bad environment;
- smart lithium battery power supply, the machine can work continuously more than 10 hours.
9 flaw detection paths
The instrument consists of nine independent flaw detection channels and one calibration channel,Can realize the rail defect detection, positioning and other operations.

A&B scan display
FD-GT-3 has type-A and type-B scanning, among which type-B scanning is the side view of the rail, which can clearly distinguish the distribution and direction of defects. Type A and type B display mutually assist each other, easy to complete the ultrasonic inspection of the rail.
Easy defect location using GPS system
The FD-GT-3 recorded all the data of the operation, including operation time, location, detection speed and distance. All information can be continued on the computer management, and can generate inspection reports directly printed.
