PURPOSE: A salinity measuring device is provided to transfer a measured salinity value to a terminal or a PC in an office of an administrator on a real time basis by measuring the salinity value. CONSTITUTION: A salinity measuring device comprises a sensor housing(10), a temperature sensor(20), a plurality of electrodes, a hollow pipe(40), an installation block(50), a driving member(60), a cylinder(70), a connection block(80), a wiper device(90), a control device(100), and a power supply unit(110). The upper part of the temperature sensor is fixed to the inside of the sensor housing and the electrodes measure salinity. The hollow pipe accommodate a cable of the electrodes and temperature sensor in the inside, thereby drawing out the cable to outside. The installation block is installed in the upper part of the hollow pipe to be faced to the sensor housing. A cylinder rod(71) of the cylinder is moved up and down by the driving member and installed to face to the sensor housing. The wiper device comprises a wiper(92) contacting to one side of the sensor housing and the wiper cleans end parts of the plurality of electrodes while moving on a surface of the one side of the sensor housing when the cylinder rod is moved up and down.
