Temperature and Oxygen Probe   

Oxygen Probe(TOS) is used in open-hearth furnace,converter and refining mainly furnace,vacuum stove with in various steel-making stove molten steels,the scene of temperature and oxygen activity measures.

The key part of oxygen probe is oxygen half-ceel,which is researched and debeloped by our company indenpendently.The outer dia.of the paper tube is 381mm,and the tube thinkness is 10mm.The total length is 1300mm or 800mm.
