Allegheny Instruments GeoVISION Heavy Duty Borehole Video System
February 19, 2014
Allegheny Instruments has updated the control panel for the GeoVISION Heavy Duty borehole video system. The Heavy Duty system utilizes a hand-reel winch to raise and lower borehole cameras to depths of 1,000 feet. The control panel is now mounted in a rugged carrying case which houses all of the system components including the power supply and controls, a 7-inch LCD monitor, on-screen depth (OSD) encoder circuitry, 12V inverter, DVD recorder and camera centralizer.
