Enhancing Visual Inspection in Hard-to-Reach Areas
In modern industrial environments, internal inspection is essential for ensuring product quality, operational safety, and efficient maintenance. However, critical components such as internal bores, pipelines, gear systems, and enclosed structures are often difficult
or impossible to inspect using conventional methods.
INSIZE videoscopes provide a reliable and non-destructive testing (NDT) solution for inspecting these confined and complex areas. Featuring high-resolution imaging (up to 1280 × 720), flexible probe configurations, and portable designs, INSIZE helps manufacturers and maintenance teams improve inspection efficiency, reduce downtime, and ensure consistent quality control.

Wind turbine gearboxes require regular inspection of internal gears and components to prevent failures and ensure long-term reliability.
● Solution
INSIZE ISV-L Series videoscope combined with portable inspection tools.
● Value Delivered
The ISV-L Series allows maintenance teams to inspect internal gearbox components without disassembly, significantly reducing maintenance time and operational downtime. Its 4-way articulated probe (±160°) enables easy navigation through complex internal structures, allowing early detection of wear, cracks, and lubrication issues. This supports predictive maintenance and improves overall equipment reliability.
3. Injection Molding Machinery

● Application
Tie bar center holes in injection molding machines require internal surface inspection to evaluate roughness conditions and corner radii (R angles).
● Solution
ISV-L + ISV-L6015 Videoscope
● Value Delivered
The ISV-L Series delivers high-resolution imaging with a 6.0 mm probe and an extended depth of field (12–200 mm), enabling clear visualization of internal surfaces. Operators can accurately assess machining quality and detect defects in otherwise inaccessible areas, improving product consistency and ensuring stable equipment operation.
4. Gas Turbine Systems

● Application
Cooling pipelines in gas turbines operate under extreme temperature and pressure conditions, making regular inspection essential to detect blockages, corrosion, and structural damage. These internal structures are often complex and difficult to access, requiring efficient inspection methods without dismantling the system.
● Solution
● Value Delivered
The ISV-L Series enables fast and accurate internal inspection without dismantling the system, significantly improving maintenance efficiency and reducing downtime. Its flexible probe design allows easy navigation through complex cooling ducts, while high-resolution imaging ensures reliable detection of defects and potential risks. This enhances operational safety and ensures the stable performance of turbine systems.
5. Rail Transit & Electric Motors

● Application
In rail transit systems, the internal components of motors and electrical systems are subject to high stress. Regular internal inspection is essential to ensure operational safety and reliability. However, traditional inspection of these confined spaces is often difficult and time-consuming.
