Inspect refractory erosion, furnace conditions and hot processes — without shutdown.
Sapphire optics and a cooled probe operate inside furnaces at extreme temperatures.
~20 MP DSLR imaging delivers sharp, live views of the process inside.
Combined air and water cooling plus a wind curtain protect the lens and camera.
Hand-carried and quick to set up — move it between furnaces and openings.
The Portable High Temperature Borescope is designed for direct visual inspection inside operating furnaces and high-temperature equipment. Using combined air and water cooling, the probe enters hot environments and transmits real-time images for maintenance and process control — no cool-down, no production stop.
Turn invisible furnace problems into planned, low-cost maintenance decisions.
Monitor wear and corrosion inside the furnace before it becomes critical.
Identify developing problems early and act before unexpected failure.
Plan repairs around the actual condition inside the furnace, not guesswork.
Prevent premature refractory damage and extend equipment lifetime.
One inspection platform across glass, metallurgy, power, building materials and chemical industries.
Circulating cooling water fills the protective cover and carries furnace heat away, keeping the inner layer at safe temperature.
Compressed air force-cools the camera and lens inside the innermost layer of the probe protective cover.
Air sprays out at the front pinhole to form a wind curtain, keeping dust and hot gas off the lens for a clear image.

Real inspections from glass, float line and refractory maintenance sites.
Real-time view of melt surface, flame shape and crown condition during operation.
Continuous monitoring along the float line without interrupting production.
Locating erosion and corrosion hot-spots to schedule targeted repair.
The probe is rated for furnace temperatures up to 2000°C, while the control/camera end stays at ≤70°C thanks to combined air and water cooling.
No. The cooled probe enters through an existing opening while the furnace is running — inspection is fully online, with no cool-down or production stop.
Compressed air at 0.3 MPa (≥0.3 m³/min) and circulating cooling water at 0.1–0.4 MPa differential (≥30 L/min), both with inlet temperature ≤35°C.
The standard portable probe is Ø55 mm × 1100 mm. Other diameters and lengths are available on request to match your furnace wall and opening.
Lead time depends on configuration. Contact us with your requirements and we'll confirm the current delivery schedule.
A DSLR camera (CMOS, approx. 20.2 MP) connects through a dedicated adapter. Camera, adapter and sapphire pinhole lens can be configured as a complete set or supplied separately.
