)  The oxygen activity of the molten steel can be measured directly and rapidly, which is helpful to determine the amount of the deoxidizing agent, and change the operation of thedeoxygenation

2) The oxygen probe is easy to operate. Measurement results can be obtained just 5-10s after inserting it into the molten steel.

Ⅲ Main Technical Indicators:
