Abstract
Provided is a hydrogen measurement sensor capable of monitoring a content of hydrogen within molten metal in real-time using an aluminum or magnesium alloy casting method, and, more particularly, a hydrogen measurement sensor having a junction structure of a solid oxygen ion conductor and a solid hydrogen ion conductor in molten metal capable of measuring a content of hydrogen within aluminum-magnesium alloy-molten metal using a new method which generates a fixed concentration of oxygen gas from a solid reference material at a high temperature by replacing a reference material of a standard gas method which is difficult to handle with a solid reference material or external air which is easy to handle or has the same effect as that of the gas reference material by using a feature in which the external air contains a predetermined pressure (0.21 atm) of oxygen.
