PROBLEM TO BE SOLVED: To simplify reagent replenishment in an electrolyte concentration measuring device, as well as eliminate a downtime of the device due to reagent replenishment.SOLUTION: An electrolyte concentration measuring device comprises: a measurement unit having an ion selective electrode, a comparison electrode and a potential measurement unit; a recording computation unit for finding the ion concentration of an internal standard solution or an analyte; and a concentration value correction and determination unit for determining whether or not the ion concentration of the internal standard solution falls within a preset range of values, as well as correcting the ion concentration of the internal standard solution found by the recording computation unit. The measurement unit has an internal standard solution bottle storage unit for storing a plurality of bottles. When bottles are switched between the plurality of bottles storing the internal standard solution by the internal standard solution bottle storage unit of the measurement unit, the concentration value correction and determination unit corrects the ion concentration of the internal standard solution found after the bottles storing the internal standard solution are switched, using information about the ion concentration before the bottles are switched.SELECTED DRAWING: Figure 1 【課題】電解質濃度測定装置において、試薬の補充を簡便化するとともに、試薬の補充による装置のダウンタイムをなくす。【解決手段】イオン選択性電極と比較電極と電位測定部とを有する測定部と、内部標準液又は検体のイオン濃度を求める記録演算部と、内部標準液のイオン濃度が予め設定した値の範囲に入っているかを判断するとともに記録演算部で求めた内部標準液のイオン濃度値を補正する濃度値補正・判断部とを備え、測定部は複数のボトルを収納する内部標準液ボトル収納部を有し、濃度値補正・判定部は、測定部の内部標準液ボトル収納部において内部標準液を収容する複数のボトル間でボトルを切り替えたときに、内部標準液を収容するボトルを切り替える前のイオン濃度値の情報を用いてボトルを切り替えた後に求めた内部標準液のイオン濃度値を補正するように構成した。【選択図】図１
