Uni-T UT663B-2m borescope

Uni-T UT663B-2m is an industrial borescope designed for use in complex spaces that are beyond the reach of the human eye. The device was created for inspections in narrow, curved and hard-to-reach areas where accurate inspection is essential without the need to disassemble components. The model is equipped with a 180° bi-directional rotating camera, a 5.0-inch display and a 2-meter cable, which allows inspections in more demanding conditions.

Better visibility and greater control over the image

The borescope has a 5.0-inch display, supports 1920 x 1080 resolution photos and records 1920 x 1080 AVI videos, allowing you to conveniently document the inspection process. The 8mm diameter camera with CMOS sensor provides a 70° field of view and a 20-100mm depth of field, allowing you to closely observe the inspected components. It also features photo capture, video recording, playback, image rotation, audio recording, and high temperature warning.

Rotating head and operation in hard-to-reach places

The most important feature of the UT663B-2m is its 180° bi-directional rotating head, which allows you to avoid blind spots and easily adjust the viewing angle. The rigid 2-meter metal cable extends the operating range and makes it easier to reach deeper spaces. This solution is especially effective where standard borescopes have limited maneuverability.

Durable construction and documentation ready

The camera meets the IP67 standard, and 8 LEDs with 4-level brightness adjustment improve visibility in dark interiors of devices and installations. The device uses a 3.7 V / 3000 mAh battery, which provides up to 4 hours of operation, and a standard 32 GB TF card allows for instant storage of photos and videos. It is a practical tool for technical, maintenance and diagnostic inspections, where ease of use and the ability to record results are essential.

It is important to know

The Uni-T UT663B-2m borescope is a specialized tool that is most useful where inspection with the naked eye is not possible - for pipework, vehicles or hard-to-reach places for home repairs. Before choosing, consider whether the cable length (2 m) is sufficient for your usual tasks and whether the ambient conditions are suitable for this type of borescope. The practicality and accuracy of use will also be determined by how often you will need it and how robust it needs to be in specific situations.

• For typical home, hobby and basic service tasks, a 2 m length is often sufficient, but in an industrial or automotive environment it quickly reaches the limits of usability.
• For frequent use in the workshop or in the field, additional protection against moisture and dust is desirable - check whether the product is also suitable for more demanding conditions.
• For less experienced users, image orientation or operation may take more time at first - expect some practice in the future for smooth use.
• The tool is best used for inspecting flat or slightly curved surfaces, but for complex navigation through long and tightly wound pipes, the range is limited by the length and flexibility of the cable.

In practice

🏠 Home use and repairs

🟢 Suitable for inspecting pipes, drains, hard-to-reach cavities, and basic diagnostics inside appliances or furniture.

🚗 Car maintenance

🟠 Suitable for basic visual inspection of engines, exhaust pipes and other hard-to-reach components, but is limited for particularly long or highly curved components.

👷‍♂️ Field work / construction site

🟡 Useful for quick visual inspection of shorter installations or commissioning of facilities, limited in larger installations due to limited cable length.

Answers to frequently asked questions

Is a borescope suitable for inspecting longer drain pipes?

It is suitable for basic inspections of shorter pipes (up to approximately 2 m), but the range will be limited for longer or deeper pipes.

How challenging is the user interface if I have no experience with borescopes?

For beginners, the operation can be a bit awkward, but with a little practice, it is simple and reliable to use.

Is the case resistant to moisture or drops?

Without additional information on protection, caution is recommended when working frequently in wet or rough conditions.

For which typical tasks is the 2 m length most useful?

For inspecting the inside of appliances, vehicles or shorter household wiring where normal access is not possible.
