Features of Seismograph Seismic Survey Equipment for Refraction, Reflection, MASW Underground Exploration

• Fast sampling----true 24-bit A/D, minimum sampling interval: 50μs for 24 channel.
• Rendering original signal perfectly----perfect amplitude and phase consistency, low distortion, band outside shearing better than 72dB (shearing frequency point changing with sampling frequency automatically, removing alias completely).
• High-speed data transfer----Transmitting data by USB port between internal industrial PC and data collector. Advanced hardware make the sampling and transferring data simultaneously.
• Powerful software function----sampling software under WINDOWS supports all kinds data acquisition of seismic methods (shallow reflection, refraction, secondary wave speed testing, micro-seismic survey, high density image and other application). Data displaying and rolling screen are very quick by using advanced graphic technique. Channel on the screen is adjustable, 128 channel maximum.
• Industrial PC configuration----PIII 533MHz, 128M memory, 40G harddisk, interior CD-ROM, 800 600TFT true color LCD, Chinese character tablet, small keyboard, photoelectric mouse, 32M Flash-Memory, double serial port, one parallel port, double USB port, mouse port, keyboard port. Seismic data collecting and transacting is convenient.
• Configuration and expansibility----DOS or WINDOWS software available. Instrument can be upgraded to 48 channel seismograph by purchasing data collecting card and software
• Stack survey support----Combined with our WZKD-1 electric stack switcher, stack survey can be realized efficiently.
• Reasonable configuration---- anti-shake, damp-proof and dust-proof design.
