Description
Overview
GAOTek Ultrasonic Flaw Detector has a user-friendly dialog interactive helps operations like Calibration, making curves, etc. All tools you need: DAC, AVG, TCG AWS, etc. Pulse Repetition Frequency: 10 Hz to 2000 Hz precise adjust, high speed scan, no miss out. High Signal to noise ratio, clear and stable echo, anti-noise design, perfect for tough working conditions. 12-digit AD, high speed sampling leads to better echo diagram with all details. Sensitive and can detect even tiny flaws. Can use probe frequency 20M perfectly. IP65 standard. Protective rubber casing. Damping support makes it stands in any angle. Battery lasts 15 hours for one charge.
