Attached are some examples we captured using our 7.5m long Boroscope (Borescope). The images were captured in a 19.05mm OD heat exchanger tube that is 13m long. The failures were found in the centre at the 6.5m mark. The Boroscope is 10mm in diameter with its own light source, hence will fit into most pipe systems. We also have far focus, close focus lenses as well as right angle lenses.
