Vibrometer - Induced Ground Vibration Monitoring Instrument (mini Seis Iii Pro)

The Mini-Seis III Pro is the ultimate vibration monitor. It is suitable for geotechnical, environmental, blast monitoring and more. It features sampling rates of up to 16K over 4 or 8 channels. There is also a 128K single channel sample rate. The unit has a 16 bit dynamic range and is very low power.

Recording modes include waveform, histogram, histogram/waveform and manual. The waveform record duration can be set from 1 to 120 seconds at all sample rates. The histogram period can be set at 1, 10, 20, 30, 40, 50, 60 or 900 seconds.

Data can be downloaded to a computer or thumb drive using high speed USB. Remote access by RS232 with baud rates up to 460800 is supported. The unit has over 3.5 GB of memory and can store up to 4096 waveform and histogram records.

The user interface is simple and easy to navigate. Soft keys provide additional options depending on the screen being viewed. Optional GPS is available to store location coordinates and provide highly accurate clock syncing.

For advanced monitoring the instrument supports the use of non-standard sensors. White can provide a hardware interface for accelerometers, strain gauges, hydrophones and nearly any other AC or DC coupled sensor.

Multiple units can be connected together in a master-slave arrangement where the master unit triggers all of the slave units simultaneously. This feature provides a common time base useful for determining propagation velocity, structure phase response and more.
