Abstract
A sensor and a measurement method for measuring hydrogen content in metal melt. The sensor has a solid proton conductor element, a reference electrode, a quasi-electrode to be measured, a reference compound, a through pipe and an insulating ceramic adhesive. The measurement method has the steps of: (1) inserting the sensor and a corrosion-resistant electrode into the metal melt, and making sure that the solid proton conductor element is fully immersed into the metal melt, the quasi-electrode to be measured is in direct contact with the metal melt and the contact surface is the electrode to be measured; (2) connecting a potentiometer and the reference electrode cable or the metal gas guide pipe to the corrosion-resistant electrode, and measuring a potential difference between the reference electrode and the electrode to be measured; and (3) calculating the hydrogen content S of the metal melt.
