Digital HD Borehole Camera is the second generation of borehole camera which designed by our company.
Digital HD camera technology can totally replace the analog  signal camera, 2 million pixel video resolution enhance the borehole camera clearance.
The camera can recognize the wall damages, defects, fissures, and falling objects inside well, real time collection and storage of dual video and shoot by matched software, also can provide the relevant testing report according to customer requirement.
The Borehole Camera is a special instrument for well testing. The instrument uses the latest television camera technology, The various states of the lower well wall can be clearly reflected on the monitor on the ground, and for the image can be saved on the disk with video recording equipment or microcomputer.Thus,it provides reliable basis for analyzing various geological conditions in the mine. The instrument is suitable for engineering geology, hydrogeology, geotechnical engineering, mining and petroleum geology and other industries.The instrument can be used to detect fissure, dislocation, falling objects, blockage of filter pipe hole and the position of fluid sand, etc. The instrument can also observe the bedrock fissures and development state as well
as the size and position of karst caves and other geological conditions in bedrock area
