What is the purpose of a borescope in inspection work?

The purpose of a borescope in inspection work is to inspect inaccessible areas. Borescopes are specialized optical devices designed to allow inspectors to see into tight or difficult-to-reach spaces. They typically consist of a long, flexible tube with a camera or lens at one end and an eyepiece or screen at the other, enabling users to visualize areas where direct line-of-sight access is not feasible, such as inside walls, ducts, or machinery.

This capability is invaluable in many fields, including mold inspection, where hidden moisture and mold growth can occur in areas that are not easily observable. By using a borescope, inspectors can gather critical visual information about these concealed spaces without the need for invasive procedures that could potentially damage structures or surfaces.

Other options, while important in their respective contexts, do not relate to the primary function of a borescope. For example, measuring temperature and humidity or air pressure involves different types of instruments specifically designed for those measurements. Providing a visual of liquid surfaces pertains to other types of optical or imaging tools rather than the unique purpose of a borescope.
