Battery-operated borescope with a diameter of 3 mm for inspecting engines and machine parts. The borescope provides new optical insights into the inner workings of engines and systems. It is the ideal tool for maintenance and servicing in workshops or industrial operations. Optical analysis with a borescope has never been easier. Simply guide the flexible cable through a hole or cavity to the area you want to inspect and view everything on the borescope's display. With its flexible guidance, lightweight design, and excellent optics, this borescope allows you to easily and early identify weaknesses and problem areas, enabling you to take targeted preventive measures without the need for extensive disassembly. This borescope is particularly versatile due to the length of its flexible part (2000 mm) and its small diameter of 3 mm. LEDs on the borescope illuminate the cavities. The waterproof lens and camera can be safely used in liquids. Make your daily work easier by using the borescope for the maintenance and inspection of your operational facilities and machines. The borescope can save images and videos for documentation on a memory card. It can also be connected to a monitor via the HDMI interface.
