Quakely-Duo is an advanced integrated seismic monitoring instrument that combines a high-performance triaxial accelerograph and a triaxial velocimeter (seismograph) into a single synchronized device. Designed for structural health monitoring, earthquake engineering, ambient vibration measurements, operational modal analysis, bridge monitoring, dam monitoring, critical infrastructure, and research applications, Quakely-Duo delivers laboratory-grade seismic measurements in a rugged field-ready enclosure.

Quakely-Duo is QuakeLogic’s flagship dual-sensor seismic monitoring instrument. It combines two independent sensing technologies within a single synchronized device: a triaxial MEMS accelerometer and a triaxial velocity sensor (velocimeter). All six channels are simultaneously digitized and synchronized, giving engineers strong-motion acceleration data and low-amplitude velocity data from the same measurement point at the same instant.
The instrument records selectable acceleration ranges of ±2 g, ±4 g, and ±8 g alongside a ±120 mm/s velocity range, with adjustable sampling rates up to 4.8 kHz. Noise performance is better than 25 µg/√Hz on the acceleration channels and better than 20 ng/√Hz (1–20 Hz) on the velocity channels, with a dynamic range of 148 dB at 16 Hz and 136 dB at 400 Hz. GPS and wireless synchronization deliver timing accuracy better than 1 microsecond, so multiple Quakely-Duo units operate as a coherent array for structure-wide measurement campaigns.
Quakely-Duo is built for the field: an IP67 CNC-machined anodized aluminum enclosure, an operating range of –30°C to +50°C, and an internal rechargeable LiPo battery providing up to 5 hours of autonomous operation. Ethernet connectivity, a smartphone interface, and real-time streaming make it compatible with modern seismic monitoring workflows.
Accelerographs excel at capturing strong shaking; seismographs (velocimeters) excel at resolving weak ambient vibrations. Most projects that need both – earthquake monitoring plus ambient vibration testing, operational modal analysis, or microtremor studies – traditionally require two instruments, two data streams, and careful time alignment. Quakely-Duo removes that complexity by integrating both sensor types in one enclosure with all six channels sampled on a common, GPS-disciplined time base.
Positioned above Quakely Pro in the QuakeLogic range, Quakely-Duo is the premium choice when a project specification calls for both strong-motion recording and high-resolution ambient vibration measurement from a single, procurement-ready instrument.
Quakely-Duo is appropriate for structural engineers, earthquake engineering consultants, seismic network operators, dam and bridge owners, operators of nuclear and LNG facilities, transportation agencies, universities, and research laboratories that need laboratory-grade acceleration and velocity measurements from a single field-ready instrument.
QuakeLogic helps customers confirm the correct measurement ranges, synchronization approach, communications configuration, installation environment, and data-processing workflow. For procurement, QuakeLogic can review the application and provide configuration-specific quotation, documentation, training, and commissioning support.
