Ultrasonic testing equipment Digital ultrasonic flaw detector
Ultrasound flaw detector RFD820
User friendly dialog interactive helps operations like Calibration,
making curves, etc.
★ All tools you need: DAC, AVG, TCG,color Bscan, AWS, Spheroidization
Rate, etc.
★ Pulse Repeatition Frequency: 20-3000Hz 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 30M perfectly .
★ High speed real-time flaw detection video recording. Unlimited USB
data storage.
★ Blue tooth connection to mobile device to generate and print
detection reports on-site.
★ 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.
