Perfect for structural health monitoring, the Gecko Pro SMA-HR is a combined recorder and acceleration sensor that can be fixed to a structure with a single central bolt. The low-noise SMA-HR uses an integrated optical feedback accelerometer providing an all-in-one package that continuously records data in a ring buffer so that when the earthquake eventually strikes you know you’ll have captured all of the data. Such high sensitivity enables the monitoring of the natural frequency and modal response of a structure, critical for improving building safety.
Paired with our Power, Alarm, and Communications box and fitted with an internal battery, the Gecko SMA-HR is the most affordable fully compliant solution to meet the 2015 DPWH guidelines on earthquake recording instrumentation for buildings. Continuous data is stored onto a local SD card and optionally telemetered to a remote computer via wireless modem or over Ethernet or WiFi.
The SMA-HR is also useful for rapid deployment of aftershock monitoring networks, it has been field tested at temporary deployment stations to show that earthquakes as low as magnitude 1.0 are clearly visible at a range of 10km from the instrument, and earthquakes as small as magnitude 0.2 within 3 km are also discernible above the typical background noise at a temporary surface station.

The Trimble S5 Total Station is built upon proven Trimble technologies like SurePoint™, MagDrive and our DR Plus EDM, helping you work more efficiently while maintaining the highest accuracy possible. Smooth and silent, Trimble MagDrive electro-magnetic technology means fewer moving parts. Trimble SurePoint ensures accurate pointing and measurements by actively correcting for unwanted movements like wind, handling, and sinkage. The Trimble DR Plus EDM allows you to measure with fewer instrument set-ups and enhance your direct reflex performance. The Trimble S5 Total Stations are available in robotic or Autolock® versions
