MULTI-CHANNEL SEISMOGRAPH FOR MASW, REFRACTION & VIBRATION MONITORING
CODE : N450
Digital engineering seismograph developed for high-precision near-surface geophysical and civil engineering applications. Designed for reflection, refraction, MASW, microtremor and vibration monitoring with true 24-bit data acquisition for maximum resolution and dynamic range.
Suitable for a wide range of active-source surveys including sledgehammer impacts, falling weight sources, spark sources and detonator shots. Capable of achieving shallow to deep exploration depths depending on geology, spread configuration and seismic source energy.
Provides comprehensive capabilities for engineering geology investigations such as bedrock profiling, layer identification, fault detection, subsurface void mapping, roadbed and embankment evaluation, and soil stiffness profiling through shear-wave velocity measurements.
Ideal for geotechnical site characterization, seismic hazard studies, urban development assessments, infrastructure planning and quality control in transportation, highways, bridges, tunnels, hydropower and industrial projects. Also suitable for groundwater, mineral, coal and hydrocarbon exploration.
Supports microtremor and ambient vibration measurements for site response analysis, building vibration assessment, construction-induced vibration monitoring and safety evaluation around sensitive structures and populated areas.
Modular architecture allows cascading of acquisition units, enabling flexible configuration from standard 24-channel and 48-channel setups to expanded multichannel arrays for MASW, refraction and microtremor array studies.
Operated through a Windows 10/7 tablet or laptop, featuring intuitive software with real-time waveform display, QC tools, stacking, filtering and direct field validation. Wireless (Wi-Fi) operation provides efficient field deployment and mobility.
Embedded self-diagnostic system automatically checks noise, crosstalk, channel consistency and system performance, generating immediate test reports to verify field readiness and ensure reliable operation before data acquisition.
