Fixed high temperature camera system usually used in vacuum furnace, blast furnace, and annealing furnace, which from steel plant, power plant and machine plant. Probe should be put through furnace, to monitor the burner flames, the wear condition of kiln lining, the material alignment and movement,melting, and sintering condition.

This camera system is made of stainless steel, with good resistance to corrosion. The camera housing is specially designed for pinhole lens, with pinhole sharp front cover, the cooling compressed air will form a air curtain to cooling the front. And the inner layer, compressed air will go through it to cool camera and lens directly, at last out of the front cover, thus will protect the whole probe from heat, dust and even slag.
