low oxygen Probe (1-100ppm)

                                           Probe low oxygen(1-100ppm)     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.   . Temperature measuring: A,) Range: 1450~1750°C B,) Tolerance: 3°C C,) Measuring Time: <4s Oxygen activity measuring: A,) Range: 1~1000ppm B,) Tolerance: >150ppm, 5ppm <20ppm, 0.5ppm C,) Measuring Time: <5s Oxygen electrical potential measuring: A,) Range: -300/+350mv B,) Tolerance: 2mv C,) Measuring Time: <5s According to the different type of probe,The probe can be divide into R and S type.
