The present invention relates to an electrochemical TRO sensor comprising: a flow cell which is installed in a ballast pipe including an inlet to which ballast water flows and an outlet from which ballast water is discharged; a measurement electrode cell which comes in contact with the ballast water flowing in the flow cell, and measures a current value; a correction electrode cell which comes in contact with the ballast water flowing in the flow cell, is operated in accordance with a preset period, and measures a current value; and a controller which compares the measurement value of the measurement electrode cell with the measurement value of the correction electrode cell, corrects the measurement value of the measurement electrode cell when the comparison value deviates from a preset error range and calculates a remaining chlorine concentration. One electrode cell is used for measurement and the other electrode is used for correction, thereby correcting a decrease in measurement sensitivity and measuring an accurate TRO.

    본 발명은 밸러스트 수가 유입되는 입구 및 밸러스트 수가 배출되는 출구를 구비한 밸러스트 배관에 설치되는 흐름 셀; 상기 흐름 셀을 흐르는 밸러스트 수와 접촉하여 전류값을 측정하는 측정용 전극 셀; 상기 흐름 셀을 흐르는 밸러스트 수와 접촉하고, 기 설정된 주기에 따라 작동하여 전류값을 측정하는 보정용 전극 셀; 및 상기 측정용 전극 셀과 상기 보정용 전극 셀의 측정값들을 비교하고, 비교값이 기 설정된 오차 범위를 벗어나는 경우 상기 측정용 전극 셀의 측정값을 보정하여 잔류 염소 농도를 계산하는 콘트롤러를 포함하는 전기화학식 TRO 센서에 관한 것으로서, 하나의 전극 셀은 측정용으로 사용하고 다른 하나의 전극 셀은 보정용으로 사용함으로써, 측정 감도 저하를 보정할 수 있어 정확한 TRO 측정이 가능하다.
