What is the primary equipment used in remote visual examination?

The primary equipment used in remote visual examination is indeed a borescope, telescope, or camera. These tools allow inspectors to visually assess areas that are difficult or impossible to access directly, such as the interiors of pipes, tanks, or other confined spaces.

Borescopes are specially designed optical devices that can navigate into tight spaces and provide real-time visual feedback on conditions that may require inspection. Telescopes can be used for distant viewing, and cameras enable the capture of images or videos for further analysis, thereby facilitating a thorough inspection process without the need to physically access the areas being examined. This approach not only enhances safety by minimizing the need for physical entry into hazardous environments but also increases efficiency and accuracy in the inspection process, allowing for detailed documentation and evaluation.

Other options, such as ultrasound instruments and X-ray equipment, are used for different inspection techniques dealing with material thickness, integrity assessments, and detecting hidden flaws, rather than providing direct visual observation. Visual acuity tests, while they may relate to the ability of inspectors to see well, do not constitute equipment for conducting remote visual examinations.
