Inspection of tubing with sectional borescope

No other sectional rigid borescope delivers such exceptional image resolution with this much length adaptability. The Lenox sectional rigid borescope is an industry standard for applications where uncompromising image quality and user control over length are critical.

This unique inspection tool is furnished as a basic 3-foot (91.4 cm) borescope with a threaded probe. By adding optional 3-foot (91.4 cm) screw-on extender sections, you can increase the working length to meet almost any requirement. Lenox sectionals feature computer designed optics and stainless steel or light weight aluminum alloy construction. They are available in a broad range of standard and custom diameters.

Every sectional comes complete with probe body and eyepiece, a viewing head, variable transformer, spare incandescent light source and a fitted protective case. And for greater performance range, you can choose from five different optional, interchangeable viewing heads (forward, circumference, right angle, retrograde and forward oblique). Inspection of turbine with sectional borescope

No matter how long your Lenox sectional scope gets, there is one thing that never changes: Image Quality. Whether it is 3 feet (91.4 cm) long or extended up to 150 feet (45.7 meters)... no other sectional borescope delivers a Sharper, Higher Resolution Image.
