Disclosed is a holder for installing the measurement electrode of a hydrogen ion concentration meter including a locker for preventing recession, which includes a stopper body to prevent the position change of a hydrogen ion concentration meter due to a decrease in friction caused by the abrasion of the hydrogen ion concentration meter induced by the correction or replacement of the hydrogen ion concentration meter buried inside. The holder for installing the measurement electrode of a hydrogen ion concentration meter including a locker for preventing recession comprises an electrode guide, a first body, a second body, and the hydrogen ion concentration meter. |
