Features: - Sophisticated circuitry with 640MHz sampling frequency enables the
system to quickly reflect the signals of the flaws and interpret
them accurately to detail no matter how weak and small they are,
which ensures real-timeness and truthfulness of the echo signals.
- Advanced square wave drive renders the device extraordinarily
penetratable with high signal-to-noise ratio when applied on high
attenuating materials or thick works. Adjustable drive pulse width,
drive voltage, and damping resistance are contributors to high
resolution of the device when used on thin works or composites.
- PIR digital filtering technique for enhancement of signal-to-noise
ratio. Probe frequency spectrum scoping gives you the overview of
the engaged probe.
- Quality 5.7" trans-reflecting TFT screen (640×480),suitable for
working outdoors or sunlighted.
- In accordance with EN12688-1:2000, long and continuous record and
storage, up for TSG R0004-2009 standards.
- Auto velocity adjustment to the materials being worked on, and
adaptation of the parameters like time delay, K value to different
probes; DAC and AVG figures could be easily organized and drawn on.
- SD card port for mass storage; USB port for extended volume from U
disk, and for extended control from keyboard or mouse, realizing
communication, data transference and paperborne output with PC.
- Ergonomics-optimized structure and appearance with multi-angledly
adjustable handle.Weighing 1.5kg, including built-in battery and
charger for easy operation and carriage.
Rail Welding-seam Purposed Tandem Scanner The rail welding-seam purposed tandem scanner--HSCQc1-H2 is
designed to detect inclusions, bores, rarefaction inside central
part of the welding seam of the rail cross-section. Features 1. The scanner is equipped with two probe chuckings movable towards
opposite direction. 2. Total soundpath remains in the steel piece of rail. 3. Put the scanner equipped with a pair of T-R probes to the
central part of the rail piece, and tune the knob as the probe will
move from the starting point of the ruler to the close-up, which
will accomplish the detection process from the head to bottom of
the cross-section of the welding seam. The depth of the flaw can be
read from the ruler. The scanner is absorptive to magnetic matters. 4. With simple structure, light weight and high durability.
Water-proofing bag is provided for convenient carry-on. 5. It can be matched up with any UT instrument with T-R connector
pairs. 6. More portable as coupled with model HUATEC FD-GT-1010 and
FD-GT-1020 and suitable for field work.
