””””WSD-2A digital
sonic instrument
””””The instrument is primarily applied for detecting concrete,
rock and core sample, and nonmetallic material such as porcelain,
graphite by sound or supersonic wave nondestructive detecting.
It can be used for intensity detection, intrinsic defect detection,
fissure detection, interface quality and rupture thickness detection,
equality detection, framework thickness detection, pile foundation
inspection, sonic logging and material elastic parameter detection
and other applications.
Features
- High reliability----built-in industrial control PC£¬ large-scale
integrated circuit design, good stability, sealed aluminum
alloy box structure, anti-shake, damp-proof and dust-proof
design.
- High automation--- quick auto-reading of sonic time and
head wave amplitude.
- Strong anti-interference: three band-pass windows provision
with multiple high-pass and low-pass filters, certain frequency
disturbance suppress, applicable under a certain extent disturbance
environment.
- Large liquid crystal display----640”Į480 resolution, applicable
to in obscuration environment.
- Flexibility of operation----new operating software with
reasonable design and convenience, clear Chinese characters
show, menu structure design, operated by scroll or keyboard
or mouse.
- Flexibility of power----AC or DC power, supplied with rechargeable
batteries£¬instrument can work over 5 hours after recharge.
- Advanced power management---- power on or off easily with
special keyboard on the panel, power cuts off automatically
if overtime by special standby mode.
- Reserves----128 MB flash disk, to memorize all kinds of
data and waveform, convenient for home analysis.
- Data unload convenience --- the data can copy directly by
Flash-Memory
- All Chinese Windows based analysis for PC or note PC: multi-function,
easy operation, generate three testing reports (confirming
the rules by China Ministry of construction).
