White Industrial Seismology Mini-Seis™ Get Quote



The Mini-Seis™ is the very definition of a great blast monitoring seismograph for an affordable cost.  It is ideal for all kinds of blast vibration monitoring and for most continuous vibration monitoring in bargraph mode.  Rugged, reliable and very easy to use, the Mini-Seis™ sets the standard for value in a seismograph.

Key Features

  • Sophisticated, non-loss data compression results in small record sizes and fast data transfer.
  • Wave form (self-trigger and manual-trigger) and continuous bar graph (histogram) modes.
  • Rechargeable internal battery.
  • Excellent power management.
  • Selectable seismic and acoustic recording range, seismic and acoustic trigger level, sample rate and record duration.
  • External seismic package and microphone interchangeable between units of like sensitivity.
  • Keypad and display for easy field setup and data review.
  • Rugged and shielded against RF interference.
  • Maintenance and calibration costs are also less.
  • Costs much less than comparable seismographs.
  • Includes convenient carrying case. Economical.
  • Can use either AC or DC power for long term monitoring.
  • Lightweight and easy to use.
