Earthquake shaking data you can count on
Our EQResponder 90 dB accelerograph is a budget considerate, proven performer during low-to-damaging levels of earthquake shaking.
Targeted design
The EQR-90 is the "best-in-class" low-cost accelerograph, measuring from just below human perceivable shaking to beyond damaging shaking. It has been specifically targeted toward providing information relevant to the interaction between earthquakes and the built environment, without the cost penalty of over-sensitivity, measuring shaking that has no effect on our built environment.
Compared to traditional solutions, the EQR-90 offers an order of magnitude reduction in total installed cost, or an order of magnitude increase in measurement points for the same project budget.
Key Features
Integrated Web Server
An intuitive self-hosted web interface provides dynamic monitoring and configuration capabilities on any device
Microsecond Precision
Built-in GNSS, Precision Time Protocol (PTP), and Network Time Protocol mean your data is always synchronised for forensic-grade reliability
Intelligent Recording System
Highly customisable filtering, triggering algorithms, pre- and post-event windows and export data formats make it simple to capture and process your desired signal
Flexible Installation
Electronic offset removal, real-time coordinate transforms and multiple communication options make fieldwork a breeze
Engineered for Integration
Seamlessly integrate with existing systems and implement hands-off management using the programmatic API
Long-Term Storage
A rolling buffer retains 90 days of full-fidelity data to ensure nothing is lost
