Single Hole Sonic Exploration Equipment
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
1.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.
2.High automation--- quick auto-reading of sonic time and head wave amplitude.
3.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.
4.Large liquid crystal display----640×480 resolution, applicable to in obscuration environment.
5.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.
6.Flexibility of power----AC or DC power, supplied with rechargeable batteries,instrument can work over 5 hours after recharge.
7.Advanced power management---- power on or off easily with special keyboard on the panel, power cuts off automatically if overtime by special standby mode.
8.Reserves----128 MB flash disk, to memorize all kinds of data and waveform, convenient for home analysis.
9.Data unload convenience --- the data can copy directly by Flash-Memory
10.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).
