Uni-T UT663B borescope

Uni-T UT663B 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 1-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 is its 180° bi-directional rotating head, which allows you to avoid blind spots and easily adjust the viewing angle. The rigid 1-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.

Same summary

The Uni-T UT663B borescope is suitable for users looking for a solution for quick visual inspection of hard-to-reach places for home repairs, small service jobs or hobbies. Due to its limited length of up to 1 m, it will best serve relatively short pipes, openings or hollow objects, while it is not the best choice for long-term professional inspections of larger objects. The compact design makes it easier to handle outdoors or in the workshop, but may require a little more patience when orienting the image for deeper openings.

Answers to frequently asked questions

What diameter and length of pipe can I inspect with this borescope?

The Uni-T UT663B borescope is best suited for inspecting openings and pipes whose length does not exceed 1 meter and whose diameter allows the insertion of the borescope head.

Is this borescope also suitable for automotive or home repairs?

Yes, a borescope is often used in minor automotive repairs and maintenance, e.g. to inspect the engine compartment, pipes or drains, where it is difficult to access with conventional tools.

Is the use of the device safe for electrical and sensitive technical parts?

Caution is advised when inspecting electrical or sensitive parts; use the device only in switched off or voltage-free areas to prevent damage to the equipment or borescope.

Do I need special skills to use the Uni-T UT663B borescope?

No special technical skills are required for basic use; only a little patience and attention to camera orientation and a basic understanding of how to read the image on an output device are recommended.

Does the image on the screen rotate or flip depending on the orientation of the borescope?

The image on the screen may actually change depending on the rotation of the device, so it is recommended to hold the borescope steady and remember the initial orientation when inserting.
