1000-1500m DSHD-12 Underground Borehole Camera

Application: It mainly used in engineering, hydrology, mining, petroleum, geotechnical, civil and other units or departments. It can be used to observe the characteristic of geologic body in drill hole, wellhole, well drilling, oil well and pile foundation etc, such as lithology, rock structure, geological structure, rock strike, faults, fissures, dissection, broken karst. Function: It is mainly used for the division of stratigraphic architecture; distinguish borehole wall cracks and karst formations status, the fractured development zone; Determine the position of karst distribution and pore long-term monitoring, etc. mainly used to test the tube breakage, well litter, filter tube hole plug in the engineering of repairing deep well. Real-time to shooting and record the deep well casing, casing wall damage and leaking status etc, and then transmit the photographed image to the ground display by a dedicated cable. Feature: 1. Waterproof, high pressure resistant, high temperature resistant 2. Easy to operating 3. Auto-focus on near and far objects simultaneously, clear images 4. Real-time image monitoring, collecting, shooting and recording.
