Seismograph Seismic Refraction MASW Equipment 24 Channels with 4.5 Hz Geophones for Sale
Product Description
WZG-12A is a 24-bit 12 Channels Seismograph, WZG-24 is 24-bit 24 Channels Seismic Equipment,
Rayleigh Wave, Shear Wave Velocity Measurement Equipment.
Seismic source for testing may be hammer, electric spark or explosion, extremely fitted for sheared wave velocity test, surface wave exploration, pier foundation test, ground micro-tremor measurement, seismic imaging, shake measurement, and refraction or reflection survey.
The seismograph applies to engineering geological prospecting, in various fields such as hydrology, electricity, railway, bridge, city construction, traffic, etc, and in petroleum, coal, uranium and groundwater exploring.
Features of Seismograph Seismic Refraction MASW Equipment 24 Channels with 4.5 Hz Geophones for Sale
- 24-bit A/D---- Maximum sampling rate is 10μs and 50μs for 3-channel and 6-channel operation respectively.
- Perfect display of original signals---- Fine amplitude consistency and phase consistency, super-low distortion, advanced high-cut filter with suppression more than 72dB (cut point changes according to sampling frequency, without false frequency).
- High-speed data transferring---- Data collection device and industrial PC (or notebook PC) are designed with USB ports, performance are much higher than other printer ports; sampling and data transferring can carry out simultaneously, owing to the advanced hardware.
- Trigger signal is available at any time to get into sampling process, for background noise is always being monitored.
- Powerful software---- Windows Operating System supports data sampling in various kinds of seismic working modes (sheared wave velocity test, surface wave exploration, pier foundation test, ground micro-tremor measurement, seismic imaging, shake measurement, and refraction or reflection survey, etc).
- Advanced technologies make swift display and fast roll possible---- Channel number to be displayed on the screen is defined by the user, maximum 128 channels; support convenient amplitude balance display and clear static time label line display.
- Flexible configuration, easily extendable---- Both DOS and WINDOWS are optional.
- Reasonable configuration---- Featuring shake proof, waterproof and dust proof.
