Accelerograph by Unquake

Description

Unquake accelerograph is equipped with low noise - low drift MEMS digital accelerometer from Analog Devices. It is particularly suited for (but not limited to) structural health monitoring. The instrument & software is designed as a cost-efficient solution for performing modal analysis and extracting the dynamic characteristics.
