Product introduction:
1.Apply to special closed circuit television of steel mill blast furnace top.
2.Using water and air cooling.
3.Probe hood use stainless steel materials, with good corrosion resistance.
4.Spiral purging, the lens does not gather dust.
5.Real time temperature curve, temperature analysis,temperature tracking display.
6.Flexible configuration setup and abundant, powerful video processing function.
7.Lens:high temperature pinhole lens, long focus.
8.Camera:high temperature special infrared camera, with high definition.
9.Easy to install: the inner gun that consisted of lens and camera cover can pull out directly, is easy to repair and maintenance.
10.Nitrogen cooling: due to the front end of the equipment need to entry the furnace, because the temperature of the furnace is high, so need to using nitrogen to cooling.
11.Equipping American imported vortex cooling technology and equipment to cooling.
12.By computer can observe feeds conditions directly or by external monitor.
