The PR20 is a high-performance computer-controlled ultrasonic pulse generator and receiver. The instrument is connected to a computer and an oscilloscope for use, assisting in utrasonic flaw detection, thickness measurement, and probe testing, etc. It has a wide range of applications in non-destructive testing (NDT) and material analysis.
The pulse generator and receiver include a Windows-based control software, allowing users to select trigger sources, transmit voltage, repetition frequency, and pulse width. Additionally, it enables switching between single/dual-crystal modes, adjusting damping and gain to meet different user requirements. The open SDK software package also allows users to develop custom applications on various mainstream Windows systems.
