Enhancing Internal Inspection Efficiency with INSIZE Videoscopes

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.

Industry Applications

1. Aerospace Components Manufacturing

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

ISV-L + ISV-L6015 Videoscope

● Value Delivered
