The Vibrock V901 seismograph is a rental solution for unattended monitoring of ground vibration events such as quarrying, demolitions, drilling, rail and traffic vibrations through its tri-axial geophone. Capable of continuous monitoring the V901 also allows the user to set threshold parameters for impulse triggered monitoring, with all results stored internally for subsequent download. The software can interrogate the instrument and provide details of the events such as Peak Particle Velocity (PPV) and Vibration Dose Value (VDV). Making this the perfect rental or hire option for short or long term applications.

The unit is self-contained in a Pelican case and runs from two batteries for long periods of time.
