TFD320PLUS ULTRASONIC FLAW DETECTOR DAC AVG & B scan Dual 4A
Ultrasonic Flaw Detector
DAC AVG & B scan Dual 4A Ultrasonic Flaw Detector TFD320PLUS for
Gate and DAC alarm& 5 MINUTES VIDEO
★ User friendly dialog interactive helps operations like
Calibration, making curves, etc.
★ All tools you need: DAC, AVG, TCG, AWS.
★ Pulse Repeatition Frequency: 20-2000Hz 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 25M perfectly .
★ High speed real-time flaw detection video recording. Unlimited
USB data storage.
★ IP65 standard. Alloy + Silica gel case, water and dust proof,
solid and lasts forever. Damping support makes it stands in any
angle.
★ Battery lasts 15 hours for one charge. Each battery has own
charging control so with two batteries it can work around the
clock.
