ST24

Product catalog summary

Overview: The ST24 is a 24-channel, 24-bit seismograph designed for various seismic prospecting methodologies, including refraction, reflection, MASW, SASW, Down-hole, Cross-hole, seismic tomography, and HVSR investigations. It features a 24-bit resolution capture card and can be expanded to 48 channels by serializing two units. The device is managed via software installed on a connected PC or notebook, allowing for easy parameter configuration.
