Structural Performance:
Precision-Engineered, Durable, Stable, and Reliable
1. Core Structural Design
1.8mm Ultra-Fine Metal Probe: Constructed from medical-grade stainless steel, featuring a diameter of just 1.8mm and a length of 200mm. It can effortlessly navigate through pinhole-sized crevices, precision tubing, and the narrow gaps between electronic components.
400 x 400P Resolution: Features a wide 120° Field of View (FOV) and a depth of field ranging from 3mm to 100mm.
Ergonomic, Non-Slip Handle: The handle is crafted from a non-slip aluminum alloy material, ensuring a comfortable and secure grip that prevents slippage, minimizing hand fatigue during prolonged operation.
Direct USB Connection Module: Features a built-in, stable signal amplification chip that connects directly to Windows PCs and Android devices via a standard USB-A port. It requires no external power source-simply plug and play. The cable utilizes a high-shielding, anti-interference design to ensure lag-free, stutter-free video streaming.
2. Core Performance Parameters
HD Imaging: Equipped with a 1/1.8-inch HD CMOS sensor delivering 400 x 400P resolution. It produces crisp, detailed imagery capable of precisely capturing minute details such as micron-scale cracks, burrs, and blockages.
Wide-Angle Direct-View Lens: Offers 120° wide-angle coverage, enabling flawless inspection of tube walls, equipment side surfaces, and the inner walls of crevices-effectively eliminating all visual blind spots.
Adjustable LED Illumination: The probe houses four built-in miniature LEDs with adjustable brightness settings. These lights provide uniform illumination even in pitch-black environments, preventing issues such as overexposure or dark corners.
Low-Power Design: USB-powered with a power consumption of just 0.5W. It operates stably immediately upon connection to a device, eliminating concerns regarding battery life and making it ideal for continuous, long-duration inspections.
Core Advantages: Exclusive for Cross-Border Markets-Precise and Efficient
Ultra-thin design, breaking space limitations
The 1.8mm ultra-thin probe can reach tiny spaces inaccessible to traditional endoscopes, such as the internal channels of precision instruments and mechanical castings, thus solving key industry pain points: "inaccessibility" and "inability to observe clearly."

Industrial-grade durability + lightweight portability
The handle weighs only 150 grams, with a compact overall design; the included Oxford cloth carrying case facilitates transportation and carrying. The metal probe is corrosion-resistant, with a lifespan far exceeding that of similar products.
Plug and play, universal device compatibility
Utilizing a universal USB interface, it supports operating systems such as Windows, Android, and Linux. No complicated driver installation is required, allowing users to quickly and easily get started.
High-definition non-destructive testing-reducing maintenance costs
Internal testing can be performed without disassembling the device, avoiding secondary damage often caused during disassembly. This significantly improves the efficiency of industrial maintenance and automotive repair while reducing labor and time costs.
Wide Range of Applications
Covering Precision Testing Across Multiple Industries

Precision Machinery
Inspecting the internal gears, bearings, and valves of aerospace, medical devices, and precision instruments for wear, burrs, and foreign object blockages without disassembling the entire machine.

Pipeline Inspection
Locating internal corrosion, cracks, and leak points in hydraulic pipelines, cooling pipelines, and gas micropipelines.

Electronics Manufacturing
Inspecting the internal circuitry, solder joints, and components of mobile phones, laptops, and precision circuit boards to troubleshoot short circuits, cold solder joints, and other faults.

Scientific Research
Observing the microstructures in the fields of biology and materials science, and monitoring the internal condition of small containers.
