1.Type of Borescope: Decide between rigid, flexible, or videoscopes. Rigid borescopes are best for straight-line inspections, flexible borescopes are more versatile for curved paths, and videoscopes offer real-time imaging and are suitable for complex inspections.

    2.Diameter and Length: Ensure the borescope's diameter and length are suitable for the inspection area. A smaller diameter allows access to tighter spaces, while the length should be sufficient to reach the target area.

    3.Image Quality: Consider the resolution of the camera. Higher resolution provides clearer images, which is crucial for accurate inspections. Look for features like adjustable focus and lighting.

    4.Lighting: Adequate lighting is essential for clear visibility. Some borescopes have built-in LED lights or light sources, while others might require external lighting.

    5.Display and Recording: For real-time viewing and recording, check if the borescope has a built-in display or if it can connect to an external monitor. Recording capabilities can be useful for documentation and analysis.

    6.Durability and Build Quality: Depending on the environment, you may need a borescope with a rugged build or one that is resistant to harsh conditions, like heat, moisture, or chemicals.

    7.Flexibility and Maneuverability: For flexible borescopes, consider the degree of flexibility and the ability to navigate complex paths. Ensure it can handle the specific inspection scenario you have.

    8.Price and Budget: Balance your requirements with your budget. While higher-end models offer advanced features, there are also cost-effective options that might meet your needs.

    9.Brand and Support: Opt for reputable brands that offer good customer support and warranty services. This ensures you have access to help and repairs if needed.
