Which device is commonly used for inspecting hard-to-see areas inside equipment?

• A. Borescope
• B. Endoscope
• C. Periscope
• D. Scope

Answer: (A)

Inspecting hard-to-see areas inside equipment is best done with a borescope. It’s a slender instrument with an optical system and a light source, available in rigid or flexible forms, that lets you look into small openings and view internal surfaces without disassembly. You can feed it through access ports to inspect for buildup, wear, corrosion, or damage, and you often view the image on a monitor or through an eyepiece. While similar devices exist, the term borescope is specifically used for industrial internal inspections of machinery, ducts, and similar compartments. Endoscopes are more associated with medical use, periscopes view from a protected position, and “scope” alone is too vague for this purpose.
