Colloidal Borescope
The Geotech Colloidal Borescope accurately measures groundwater velocity and direction in real-time. Using proprietary technology, the Colloidal Borescope incorporates a down-well sensor set to depth-specific intervals and a live-view AquaLITE software that captures and records thousands of data points per minute yielding statistically assured preferential flow data.
- Observes flow at a pore scale for measuring velocities ranging from 0 to 30 mm/sec
- Generate flow and velocity models using existing wells – avoiding added costs associated with installing additional wells or piezometers
- Identify flow direction and velocity in real-time
- Capture statistical summary report that includes well number, date, vector analysis and more
Components
- Borescope Probe – fully integrated colloidal view video microscope with magneto-resistive digital compass enclosed in a protective 300 series stainless steel housing.
- Bulkhead Down Well Cable – reinforced composite video underwater camera cable incorporating Kevlar longitudinal strain relief and polyurethane outer jacketing. Down well cable lengths are available from 100' (30m) to 1000' (305m)
- Geotech Portable Reel – transporting and storing the down well cable and Borescope probe
- Camera Control Unit – featuring camera and lighting power supplies, serial data connection for digital compass via USB, and transmission of live down well video using a 54mm express card
- Extension Cable – connects camera control unit to the portable hand reel, used with systems that include 200 feet or more of down well cable
- AquaLITE Software – allows user to live-view water flow direction, velocity or combined graphs, and statistical summary reporting. AquaLITE also features fully configurable video signal quality, ground water quality, and other aquifer characteristics
