| Boroscope: |
An instrument which can see inside wall cavities, ventilation ducting and inaccessible areas, to assess and inspect for surface contamination or the condition of the surrounding surfaces. Some boroscopes are battery light operated and they have a telescopic 45 degree angled mirror on top to inspect surfaces, while more sophisticated boroscopes work with laser-like precision, they can see for long distances and closer detail. These boroscopes can be connected to video recording units for later playback. |
