With intense fiber optic illumination and crisp image delivery through high-resolution quartz optical fibers, these borescopes are ideal for any inspection requirements. Fiber optic construction tolerates a ±15° shaft deflection during inspection. Built-in light allows viewing through walls and in dark bores and cavities. The adjustable focus clarifies the detail of the inspection area. Rugged steel and aluminum construction provide protection in the most industrial applications. What’s included: two C batteries and carrying case.
