TRITON Accelerograph – Advanced Seismic & SHM Solution for Urban Buildings
The TRITON Accelerograph is a high-performance seismic recorder engineered for permanent building instrumentation and Structural Health Monitoring (SHM) in high-seismic urban environments, including San Francisco and Los Angeles. Designed for reliability, precision, and scalability, TRITON delivers accurate strong-motion and ambient vibration data for both regulatory compliance and real-time post-earthquake assessment.
