The GT-2 is full digital, color display and portable ultrasonic testing instrument, which is specifically designed for detecting on-site rails of 43~75kg/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.

  • Improve and upgrade easily.
  • Light, ergonomically designed for easy operation on site.
  • Simple operation with only six pressing keys and an intellectual knob.
  • 5.7" color TFT display with excellent clarity and adjustable brightness, glare shield is no necessary even in the sunlight.
  • Display each channel's waveform in different color, flaw waveform enables the audible warning alarm (horn) or lighting alarm.
  • Clearly observe all channels' waveforms or a specified channel's waveform with 28 display modes.
  • The first 10-channel instrument meets the requirements of flaw detection.
  • Advanced circuit technology, flexible gain curve can be saved and recalled to meet the special need.
  • Can store up to 1000 data sets, 100 recordings, and long time full work recording, and transfer to U disk at any time.
  • Configurations can be saved and recalled without repetition adjustment.
  • Data communication and software upgrade can be realized with PC, and all settings can be printed directly using printer.
  • Real time control with computer, use logic circuit instead of analog control circuit, digitally display sound path, horizontal and depth locations, the operator can obtain the detailed flaw detection information immediately.
