Features:
1. 24 Channels Seismograph: The instrument is equipped with 24 channels, allowing for simultaneous data acquisition from multiple seismic sensors. This enables researchers to gather a wide range of data points and capture detailed information about subsurface characteristics.
2. MASW (Multichannel Analysis of Surface Waves): The instrument incorporates the MASW technique, which analyzes surface waves to determine shear wave velocity profiles. This feature is valuable for assessing soil conditions, identifying potential hazards, and evaluating the stability of geological formations.
3. Refraction and Reflection Seismic Survey: The instrument supports both refraction and reflection seismic survey methods. Refraction surveys help determine the depth and velocity of subsurface layers, while reflection surveys provide insights into the interfaces and structures within the subsurface. This dual capability allows for comprehensive analysis of geological features.
4. User-Friendly Interface: The instrument features a user-friendly interface that simplifies data acquisition and processing. It offers intuitive controls, clear visualization of data, and easy-to-use software, ensuring that researchers can efficiently operate the instrument and interpret the collected seismic data.
