Description
Overview
GAOTek ultrasonic crack & flaw detector offer state of the art technology that is compact and lightweight. It is suitable for various detection like in forged pieces, welding lines, airplane parts.
Features
- Small dimension, lightweight, portable, fully-sealed, highly – reliable design especially suitable for working outdoors
- Bright, high resolution (640 × 480) color TFT display realizing the best measurement result in similar products
- High-performance square wave pulser with a tuning option allows the operator to tune the pulse width of the square wave pulse to optimize transducer performance. This maximizes signal-to-noise and penetration in difficult materials such as highly-attenuated materials or thin workpieces
- LAN port allows remote data transfer and management. It provides management to instrument parameters when the instrument is used as an independent square wave pulse
- Automatically test the transducer frequency, and tune the pulse width of the square wave pulse to optimize transducer performance
