What device is essential for inspecting areas that are inaccessible by other means?

A borescope is essential for inspecting areas that are otherwise inaccessible due to its design, which allows for visual inspection in tight or confined spaces. It consists of a long, flexible tube equipped with a camera and light source at the end. This enables mold specialists to observe conditions inside walls, ducts, and other enclosed areas without needing to create large openings or similar invasive measures.

The borescope’s ability to provide a live view of potential problem areas is invaluable in mold inspection, where visibility of hidden moisture or growth is crucial for an accurate assessment. This capability is particularly important when assessing structural components that are not easily reachable or visible from the exterior.

In contrast, while thermocouples detect temperature, barometers measure atmospheric pressure, and hydrometers gauge liquid density, none of these tools can substitute for the direct visual inspection that a borescope facilitates. Therefore, the borescope stands out as the required tool for situations requiring access to confined or obstructed areas.
