Terraplus is pleased to introduce the Atom Passive Seismic System, now available with a 3-channel option.

The Atom-3C is designed to obtain 3-component microtremor measurements for HVSR surveys (with one unit) as well as for joint Rayleigh-Love wave analysis (with multiple units deployed in a distributed array). The system is unique in that it does not rely on traditional and heavy spread cables. Users are no longer constrained by preset spacing/geometries or by site conditions such as high traffic areas, roads, and driveways.

The Atom-3C is a complete solution, composed of individual acquisition units, each with 24-bit A/D conversion, GPS-controlled timing, 8 GB of internal data storage and an adjustable sample rate. 2Hz and 4.5Hz 3-component geophones are also available as an option.
