CTS-9008HT rail weld ultrasonic flaw detector - portable, easy to use and reliable
The rail weld ultrasonic flaw detector specially made according to TB/T 2658.21-2007 Rail Weld Ultrasonic Flaw Detection Operation, a standard of the Ministry of Railways, can simultaneously connect various probes required for rail weld ultrasonic flaw detection, preset flaw detection parameters, on-site flaw detection, one button switch, fast and simple, excellent performance, and powerful functions. It is the first choice for rail weld ultrasonic flaw detection.
| Number | Interface | Detection position |
