GT120B 4-Way Videoscope Inspection | 2mm Probe | 4-Way | 5 Probes | WiFi HDMI

GT120B 4-way videoscope inspection — the precision NDT tool with active articulation in 4 planes (4-way) for non-destructive inspection of pipes, engines and complex industrial components with diameters of 4–200mm. With five available probe diameters (2mm / 2.8mm / 3.9mm / 6mm / 8mm), a cable made of 5 layers of anti-abrasion tungsten wire and the integration of four technologies — optics, precision mechanics, electronics and imaging — this 4-way videoscope inspection navigates through the most complex internal geometries of precision industrial components, where 2-way articulations cannot reach.

The 4-way articulation of this 4-way videoscope inspection — the absolute differentiator from all other systems in the Jiutai lineup from Uzinex — controls the probe simultaneously up, down, left and right, allowing navigation through the S-bends, branches and changes of direction on two perpendicular planes of the pipes and internal channels of components. The 2mm probe accesses openings with diameters under 3mm — injection capillaries, bearing lubrication circuits and the cooling passages of turbine blades inaccessible to any other system in the Jiutai lineup. Key Advantages of the GT120B 4-Way Videoscope Inspection

• 4-way articulation — navigation on all planes, unique in the lineup: The GT120B is the only 4-way videoscope inspection in the Jiutai lineup available at Uzinex. The 4-plane articulation allows orienting the probe up, down, left and right from the control handle — essential for inspecting components with internal geometries across multiple planes, such as engine crankcases, pump casings and complex foundry structures where bends follow one another on perpendicular axes.

• 2mm probe — the thinnest in the entire Jiutai Uzinex lineup: The 2mm probe diameter of the GT120B allows access into openings with a diameter under 3mm — thinner than the 2.8mm probe of the GT160. The injection capillaries of fuel injectors, the lubrication circuits of precision bearings and the calibration openings of measuring instruments become visually inspectable without disassembly.

• 5 probe diameters: 2 / 2.8 / 3.9 / 6 / 8mm: The GT120B set of five probes — with one more diameter than the four of the GT160 — fully covers the range from 4mm to 200mm with a single platform. Each probe is available in a front and a side version, providing axial and radial viewing of any inspected internal area.

• Integration of 4 technologies: optics + precision mechanics + electronics + imaging: The GT120B integrates four distinct technical domains into a single portable system: optics with an HD sensor, the precision mechanics of the 4-way articulation, the control and image processing electronics and imaging with live transmission. This integration is explicitly cited by Jiutai as a distinctive technological value over systems with a single dominant technology.

• Waterproof keypad — operation in humid environments: The waterproof keypad of the GT120B allows operation in environments with high humidity, condensation and splashes — aircraft maintenance hangars, marine repair workshops and wet testing laboratories — without protecting the control unit or limiting its access to the recording and editing functions.

• 5-layer tungsten cable — maximum resistance to torsion and abrasion: The cable structure of 5 cross-layered tungsten wires ensures resistance to the repeated torsion of the 4-way articulation and to the abrasion of the hard internal surfaces of foundry and forging components. Tungsten guarantees the probe's lifespan in the intensive use of industrial production.

• Integrated WiFi + HDMI — complete connectivity for collaboration: WiFi transmission allows sharing the live image with a second specialist remotely for real-time collaborative diagnosis. HDMI allows projecting the image on an external monitor for group analysis or NDT training sessions — both functions present on the GT120B, as on the GT160.

• Detachable lithium battery — unlimited sessions with spare batteries: The lithium battery detaches and is replaced instantly without a forced shutdown — continuous inspection sessions in industrial production are not interrupted by recharging cycles. The effective autonomy is limited only by the number of available spare batteries.

Technical Specifications — GT120B 4-Way Videoscope Inspection

Applications — Where the GT120B 4-Way Videoscope Inspection Is Used

A 4-way videoscope inspection from the GT120B series is the preferred tool of aerospace maintenance engineers who inspect the blades of air turbines, the cooling channels of jet engines and the structural members of the aircraft cell through standard access openings — without disassembly. The 4-way articulation allows navigating the probe through channels with bends on two perpendicular planes specific to the internal geometry of aviation engines, where a 2-way probe jams or delivers an incomplete image of the curved wall.

In the automotive industry and in the production of hydroelectric and wind turbines, this 4-way videoscope inspection is used to inspect crankcases, engine blocks, hydraulic pipes and transmission components without dismantling the unit. The 2mm probe accesses the injection openings and the lubrication circuits of precision bearings with diameters under 3mm — inaccessible to any other system in the Jiutai lineup from Uzinex.

Quality departments in the petrochemical, pharmaceutical, food and precision foundry industries use systems such as the GT120B 4-way videoscope inspection for the structural integrity audits of critical components, the inspection of welds inside pressure vessels and the verification of the internal surfaces of injection molds, in accordance with international standards for non-destructive inspection. The waterproof keypad allows complete documentation even in humid or condensation-prone work environments. GT120B 4-Way Videoscope Inspection versus GT160 — 4-Way vs 2-Way

Both systems are industrial videoscopes with a flexible articulating probe, a 5-layer tungsten cable and WiFi/HDMI. The decisive difference for selecting the model is the type of articulation and the minimum probe diameter:

• Articulation: GT120B — 4 directions (up/down/left/right) | GT160 — 2 directions (up/down)

• Minimum probe diameter: GT120B — 2mm | GT160 — 2.8mm

• Number of probes: GT120B — 5 sizes | GT160 — 4 sizes

• Screen: GT120B — 4.3 or 5.7 inch | GT160 — 3.5 or 5.7 inch

• Lighting: GT120B — 50,000 LUX constant | GT160 — 20,000–100,000 LUX adjustable

• Optimal application: GT120B for internal geometries with bends on two perpendicular planes | GT160 for pipes with bends on a single plane and variable lighting

Frequently Asked Questions about the GT120B 4-Way Videoscope Inspection

What does 4-way articulation mean and why does it matter versus 2-way?

2-way articulation controls the probe on a single plane — bending it forward/backward or left/right, but not simultaneously on both axes. The 4-way articulation of this 4-way videoscope inspection controls the probe on both perpendicular axes simultaneously — up, down, left and right independently or combined. This makes the GT120B a 4-way videoscope inspection capable of precise orientation at any angle in any three-dimensional bend, without physically rotating the unit or repositioning the inspected component. What is the minimum channel diameter the GT120B can inspect?

With the 2mm probe, the GT120B inspects channels with diameters from 4mm. The 2mm probe is the thinnest in the entire Jiutai lineup from Uzinex and allows access into injection capillaries, the distribution openings of lubrication liquids and calibration passages with diameters under 3mm in precision industrial and aerospace components. How to choose between 4 probes and 5 probes versus the GT160?

The GT120B adds the 2mm probe to the set of four of the GT160 (which starts at 2.8mm). If your inspections do not include channels under 3mm in diameter, both systems are equivalent in terms of the diameter range covered. If you work with aerospace components, fuel injectors or precision instruments with openings under 3mm, the GT120B is the only choice in the lineup. Does the waterproof keypad add anything over the standard keypad of the GT160?

The waterproof keypad of the GT120B allows full use of the recording, editing and navigation functions in environments with high humidity, active condensation and accidental water jets — without protecting the unit or wearing special gloves. The GT160 has a standard keypad that requires dry hands and protection in humid environments. For maintenance on board ships, in repair workshops with water cooling or in condensation-prone environments in the food industry, the waterproof keypad of the GT120B is a direct operational advantage. The 1.5–10m probe length — how to choose the right length?

The minimum length of 1.5m covers inspections of engine components accessible through the spark plug or inspection openings of the block; 5m reaches the deep bends of transmission crankcases and pressure vessels; 10m is the maximum length for the service pipes of industrial installations. The length is configured to order depending on the maximum inspection depth required by your specific applications. Why Buy the GT120B 4-Way Videoscope Inspection from UZINEX?
