AquaVISION provides services and instrumentation that measure groundwater velocity, direction and particle size all in real time. They accomplish these difficult tasks by using proprietary hardware and software known as the “AquaVISION Colloidal Borescope System.”
 
AquaVISION’s Colloidal Borescope System was developed by a team of research scientists to accurately determine groundwater velocity, direction and particle size in real time. Current down hole technologies only allow for a few groundwater flow measurements per day. The AquaVISION Colloidal Borescope System yields thousands of data points per minute for hours of statistically assured data.
 
AquaVISION’s Colloidal Borescope System provides a direct means of accurately determining groundwater flow direction and velocity. The Borescope measurement technique uses existing monitoring wells for assessment and thus avoids the cost of additional wells and piezometers.
  • Colloidal view video microscope with magneto-resistive digital compass for viewing of groundwater speed and direction.
  • Camera control unit for borescope probe incorporating camera and lighting power supplies, serial data connection for the digital compass (USB), and transmission of live downwell video (Express Card, ~54mm).
  • Includes hand reel, carrying case, camera control unit, probe, video card and drivers, relevant cables and connectors.
  • AC and DC power cords for convenient, versatile power source operation.
  • Reinforced composite video underwater camera cable incorporating Kevlar® longitudinal strain relief and polyurethane outer jacket.
  • Cable lengths of 100-1000 feet (200' standard)
  • 20' splash proof extension cable for connecting camera control unit to reel on systems 300' and longer.
  • AquaLITE software
  • Detailed operation manual with full instructions on how to operate the instrument.
