Tromino ZERO
The Tromino BLU ZERO is a small, lightweight, 3-channel, all-in-one seismograph specifically designed for the dynamic characterization of subsoils with the highest accuracy and the lowest effort. This very adaptable device has applications for both geology and engineering (modal analysis for structures). Typical geologic uses might be:
