GT-2  Ultrasonic Rail Flaw Detector is full digital, color display and portable ultrasonic testing instrument, which is specifically designed for detecting on-site rails of 4375kg/m. 


It can detect various harmful flaws in the rail head, web and bottom and features of excellent expansibility, high reliable and efficient performance to meet challenging inspection requirements. The new probes’ arrangement is suitable for detecting long rails and the misoperation errors can be greatly reduced using high effective data processing. 

The on-site flaw data management has been greatly strengthened with two level management modes. The perfect electronic document can be realized with flaw, full work and dynamic recordings functions as well as communication function. 

The GT-2 is one of the key means for railway safety and marks an epoch in application.
