This Strong Motion Accelerograph Seismic Recorder is a professional-grade instrument designed to capture and record high-intensity ground acceleration caused by earthquakes, structural vibrations, or industrial motion events. The unit includes a triaxial accelerometer (X, Y, Z axes) mounted on a precision sensor deck, allowing accurate measurement of motion in three dimensions. The internal electronics support triggered and event-based recording, making it suitable for engineering analysis, seismic research, and infrastructure monitoring. Housed in a rugged industrial enclosure, this instrument is intended for long-term field deployment in buildings, bridges, facilities, or monitoring stations. Communication and configuration are supported through an RS-232 serial interface, commonly used in scientific and industrial data systems. This listing is offered as a generic seismic accelerograph and is ideal for educational institutions, laboratories, collectors of scientific instruments, or professionals familiar with seismic data acquisition systems.
