Product Navigation
KW-4 digital ultrasonic flaw detector is a multi-channel ultrasonic detector using the latest digital integration and artificial intelligence technology. The instrument is easy to operate and has powerful function. The three detection systems of passenger car axle, passenger wheel rim, and freight car axle integrated in the machine can meet the needs of different customers in the railway system.
→ Use touch screen to input information, using high-brightness TFT true-color touch display
→ Eight flaw detection channels can be switched freely, and the corresponding flaw detection process files can be automatically transferred at the same time
→ The instrument has built-in flaw detection process of each shaft type
→ Can preview and print railway system standard report
→ Inspection of passenger car axles, passenger wheel rims, and truck axles, one machine equipped with three systems, without mutual interference
