Industrial endoscope with a 4.5-inch color LCD display is a professional tool for visual inspection and diagnostics in hard-to-reach places. The device is equipped with an ultra-thin camera head with a diameter of only 3.9 mm, allowing it to penetrate narrow gaps, holes and cavities without disassembling equipment or damaging structures.
The endoscope camera provides high Full HD resolution of 1920x1080 pixels, delivering a clear, detailed image on a bright color LCD screen. This allows you to accurately identify defects, cracks, corrosion, foreign objects, or assess the condition of internal surfaces.
An important advantage is the high IP67 protection rating, which applies to both the camera and the display. This means complete protection against dust and the ability to be immersed in water up to 1 meter deep for a short time. The endoscope can be safely used in conditions of high humidity, dust, and also for inspecting fluid-filled systems.
To expand functionality, the delivery set includes three practical attachments:
- Mirror attachment – allows inspection of side surfaces and cavities at a 90-degree angle relative to the camera axis, which is critical when working in confined spaces.
- Hook attachment – designed for retrieving small objects, wires, debris from hard-to-reach places.
- Magnetic attachment – helps quickly locate and retrieve steel or iron parts (bolts, nuts, tools).
The display is equipped with a slot for a microSD memory card up to 32 GB (card not included). This feature allows you to record photos and videos of inspections directly onto the memory card for subsequent analysis, reporting, or consultation with specialists. Saved materials can be downloaded to a computer via a USB cable or directly via the memory card.
The endoscope is equipped with a flexible and durable 5-meter long probe, enabling inspection of objects at a significant distance from the access point. The probe remains flexible at low temperatures and is resistant to mechanical stress.
For high-quality illumination of dark cavities, the camera head is equipped with six LEDs with adjustable brightness. This provides optimal object lighting depending on conditions and prevents overexposure. Additionally, the top of the display housing features a powerful LED flashlight for illuminating the work area, controlled by a separate power button.
The device is powered by a built-in 2600 mAh battery, ensuring long-term autonomous operation. Charging is done via a modern USB Type-C connector (cable included). ATTENTION: It is prohibited to use fast chargers (Quick Charge, Power Delivery, etc.) from modern smartphones and tablets that output voltage and current higher than 5V and 1.5A for charging. Using such chargers may damage the device. It is recommended to use charging blocks with parameters of 5V/1A (or 5V/1.5A), similar to old phone models, or USB ports of computers and TVs.
