The present invention is to provide a total residual oxidant (TRO) measurement device (1) for measuring a TRO in the ballast water of a ship and an installation structure thereof. According to the present invention, the TRO measurement device (1) comprises: a sensing chamber (4) formed between a sensor body (2) and a protective cap (3) coupled to one end of the sensor body (2) in which a plurality of electrodes (2) for detecting the TRO and pH of ballast water of a ship and a temperature sensor for measuring a temperature are installed in one end to be exposed; several access holes (5) penetrated in a part or the whole of the protective cap (3); and an ultrasonic generator (6) fixed in one end of the sensor body (2) to discharge the ballast water of the ship introduced into the sensing chamber (4) through the access holes (5) through the access holes (5). In the installation structure of the TRO measurement device (1) according to the present invention, the TRO measurement device (1) is coupled to one end of a connection valve (8) flange-coupled or thread-coupled to an installation hole (11) or an auxiliary installation hole (11′) penetrated in one side of a transfer pipe (10) or an auxiliary transfer pipe (10′) through hot tapping such that the protective cap (3) can be positioned inside the transfer pipe (10) or the auxiliary transfer pipe (10′). Thus, the present invention increases measurement accuracy by blocking foreign materials while the inflow pressure of the ballast water of the ship is dropped by the protective cap (3) having the access holes (5), improves operational reliability while smoothly introducing and discharging the ballast water of the ship with a simple structure, and automatically cleans the end of the electrodes (21) and the temperature sensor (22).
