★Probe calibration, curve making and other operations are prompted
by the dialog box in the whole process, no need to read the manual
★ All tools included what you need: DAC, AVG, color Bscan, AWS,
etc.
★Pulse Repetition Frequency: 30-3000Hz,accurate adjustment, high
speed scanning, never missing detection
★ High Signal to noise ratio, clear and stable echo, anti-noise
design, perfect for tough working conditions
★ 10-digit AD, high speed sampling leads to better echo diagram
with all details. Sensitive and can detect even tiny flaws
★ Crystal clear true-color display. Helpful user interface makes
the operation much easier.
★ High speed real-time flaw detection video recording. Unlimited
USB data storage.
★ Blue tooth connection, the mobile APP generates on-site flaw
detection report and realizes printing
★ 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.
