A glass electrode is capable of measuring a cation concentration of a test solution. The glass electrode includes a flat sensitive glass body sensitive to ions, a base body formed of a glass tube housing an internal solution, and a fixation layer used to sealingly attach the sensitive glass body to an end surface of the base body. A resistance value of the fixation layer is equal to or higher than a resistance value of the sensitive glass body. A liquid property measurement device is equipped with the glass electrode.

An oil degradation meter and a method for evaluating oil degradation are provided, in which a user is enabled to arbitrarily set a degradation of oil/fat using an acid value (AV value) as an index, and capable of learning a replacement time of oil/fat easily with a stable reproducibility, even in a case where a condition such as a moisture amount in food (deep-fried food) is different. In a setup procedure, an acid value (AV) of unused oil/fat is set to 0, a dielectric constant (D) at that time is measured and recorded, a dielectric constant (D) of oil/fat at a replacement time under a specific oil/fat usage condition is measured, and it is recorded along with an acid value (AV) at that time, and in a measurement procedure, a dielectric constant (D) of the sample oil/fat is measured, and an acid value (AV) of said sample oil/fat is calculated based on the dielectric constants (D, D) and the acid value (AV) recorded in said setup procedure, according to a calculation formula of [AV=AV&#xd7;{(D&#x2212;D)/(D&#x2212;D)}].
