Micro-Diameter Video Borescope - QualiScope™ M

The QualiScope™ M micro-diameter video borescope accesses openings that conventional scopes cannot enter. Its probe range begins at 0.9 mm and extends to 6.0 mm across eight sizes. A single main unit works with interchangeable insertion tubes through a detachable connector, allowing technicians to change probe diameter and length without switching handsets. Fiber-optic illumination and a 120° field of view produce bright, clear images on a 5-inch high-definition display. The slimmest probes fit into fuel injectors, small holes, and precision components that larger scopes cannot reach.

Steering capability depends on the probe. The finest models have fixed tips, mid-range probes offer bi-directional bending, and the larger probes provide 360° omnidirectional control, all with a 160° to 180° bending angle. A virtual ruler measures features directly on the screen, while freeze, zoom, flip, and playback functions help the operator examine defects closely. WiFi, HDMI, and Type-C ports send live video and files to monitors and computers. A high-temperature alarm alerts the operator before heat can damage the probe.

A rechargeable lithium battery pack supports online charging and delivers a minimum of four hours of runtime per shift. The waterproof, oil-resistant insertion tube holds up in automotive, aerospace, rail, shipbuilding, power, and petrochemical environments. Buyers can select the diameter, length, and steering type that suit the target, and custom configurations are available on request.

Micro-Diameter Video Borescope - QualiScope™ M Applications

The Micro-Diameter Video Borescope is designed for remote visual inspection in the smallest and most confined spaces, where probe diameter determines whether the camera can enter at all.

  • Fuel Injector and Nozzle Inspection: guides a 0.9 mm or 1.2 mm probe into injector bores and spray holes to look for deposits, wear, and blockage
  • Precision Manufacturing and Machined Parts: examines small drilled holes, cross-bores, and internal threads for burrs, chips, and surface defects
  • Automotive and Engine Service: views cylinders, valves, and coolant passages through narrow ports to detect wear, scoring, and carbon buildup
  • Aerospace and Turbine Inspection: accesses engine cooling passages, blades, and vanes through small access holes
  • Pressure Vessels and Heat Exchangers: surveys tube interiors and internal welds for corrosion, pitting, and cracking
  • Rail, Shipbuilding, and Heavy Equipment: checks welds, castings, and hydraulic bores during manufacturing and maintenance
  • Power and Petrochemical Plants: inspects pipework, valves, and vessel interiors for corrosion and deposit formation

Micro-Diameter Video Borescope - QualiScope™ M Key Features

The Micro-Diameter Video Borescope pairs an ultra-thin probe range with interchangeable tubes and on-screen measurement for detailed inspection of the smallest cavities.

  • Ultra-Thin 0.9 mm Probe: the finest tube in the eight-size series enters injector bores, spray holes, and micro-cavities that larger scopes cannot access
  • Eight Interchangeable Tubes (0.9 to 6.0 mm): a detachable connector lets one main unit switch between probe diameters and lengths, so a single system covers a broad range of openings
  • 5-Inch High-Definition Screen: displays sharp 1280 × 720 images for direct viewing during inspection
  • Virtual Ruler Measurement: places an on-screen scale over the image to size cracks, pits, and other features against a reference
  • Fiber-Optic Illumination: a rear-mounted high-power LED sends light down the probe, providing even lighting and a slim, cool tip
  • Steering by Model: fixed, bi-directional, or 360° omnidirectional control with a 160° to 180° bending angle, matched to probe size
  • WiFi, HDMI, and Type-C Connectivity: streams live video and transfers files to monitors, tablets, and computers
  • Waterproof, Oil-Resistant Tube: the insertion tube withstands wet and oily environments without damage
  • High-Temperature Alarm: sounds when the temperature exceeds the threshold, protecting the probe
  • Capture and Review Tools: freeze, zoom, flip, capture, and playback help the operator study and document defects
  • Rechargeable Battery, 4-Hour Runtime: a dedicated lithium pack with online charging keeps inspections going

Theory and Method

Probe diameter is the first consideration when selecting a borescope, because the tube must fit through the opening before anything else matters. Shrinking a probe to 0.9 mm leaves very little space for the camera, wiring, and light path. For that reason, the finest models use a fixed, straight tip and route light through optical fiber to keep the diameter small. The detachable connector allows one handset to drive any tube in the series, so the operator can match diameter and length to the job rather than purchasing a separate scope for each.

Steering scales with diameter for the same reason. The thinnest probes run straight, mid-size probes add bi-directional bending on a single plane, and the larger 2.8 mm, 3.9 mm, and 6.0 mm probes articulate a full 360° through a 160° to 180° bending angle. Control wires inside the tube pull the tip toward the target, and the wider tubes provide the space needed to house the additional wires that omnidirectional control requires.

Rear-mounted LEDs send light through optical fibers to the tip, which keeps the front end slim and places the heat source away from the camera. The system presents a 1280 × 720 image on the 5-inch screen, where a virtual ruler overlays a scale so the operator can size a crack or pit against a known reference. Depth of field varies by model, ranging from a fixed 3 to 30 mm on the fine probes to 12 to 200 mm on the 6.0 mm probe.
