This is a demo unit we used for demo how to use RFD820 to our users. With new calibration certificate and new battery. Very clean, just like new.
RFD820 Ultrasonic flaw detector |
|
★ User friendly dialog interactive helps operations like Calibration, making curves, etc. ★ All tools you need: DAC, AVG, TCG,color Bscan, AWS, etc. |
|
★ High Signal to noise ratio, clear and stable echo, anti-noise design, perfect for tough working conditions. |
