Main specifications:

True 24-bit A/D- fastest sampling rate is 10μs and 50μs for 3 or 6 channels operation.

Perfect display of raw signal- Fine amplitude and phase consistency, super-low Distortion, advanced high-cut filter above 72dB (cut point changeable as sampling frequency, complete delete the possibility of false frequency).

High-speed data transfer- fast USB port connection between device and computer, good performance above other printer ports, unique in China; sampling and transferring simultaneously with advanced hardware.

Momentarily acceptable of trigger signal for sampling during background signal monitoring.

Powerful software- WINDOWS version supports each kinds of seismic working modes data sampling (such as surface wave test, shear wave velocity testing, earth vibration measurement, high density imaging, refraction and shallow reflection). Advanced technique makes the display and scroll very fast; adjustable channel number, maximum 128; convenient amplitude balance display; clear static time ticks.

Flexible configuration, easily extendable-DOS and WINDOWS Version optional.

Reasonable structure layout- anti-quake, anti-humidity, anti-dust.
