Our industrial videoscopes are often applied in the regular inspection of turbines, blades, combustion chambers and aircraft bodies. Additionally, they can also be used for rocket engine R&D and manufacturing process quality control observation. A videoscope is an important tool for routine maintenance and inspection of aircraft, and the only way to detect the internal conditions of aircraft components without disassembling the engine. This avoids the cost of engine decomposition, dismantling, transportation and other costs as well as the loss of aircraft shutdown, minimizing maintenance costs and time. Meanwhile, videoscopes serve as intuitive, accurate, simple and easy to operate solutions to detect the damage of internal components of the engine as soon as possible, which can effectively identify and eliminate potential safety hazards while planes are on the ground.
