Product introduction:

1.Apply to all kinds of blast furnace.
2.Tuyere for 24 hours constant video surveillance.
3.Probe hood use stainless steel materials, with good corrosion resistance.
4.Tuyere camera probe is very compact and easy to maintain and dismantle. 
5.Probe install behind tuyere mirror spectroscope,through the spectroscope can still achieve manual inspection.
6.Probes can interchange, a camera probe can be installed behind the multiple tuyere mirror, achieve monitoring for the tuyere in need to cutting investment.
7.Lens: high temperature pinhole lens, long focus.
8.Camera: Miniature color camera, high definition, horizontal resolution not less than 2 megapixels
9.Spectroscope: the rear end of the protective cover is equipped with a spectroscope system. In addition to the image displayed by the monitor in the central control room, on-site inspectors can also observe through the spectroscope in real time

10. Nitrogen cooling: Since the front end of the equipment is close to the observation hole and the temperature is high, nitrogen cooling is needed
