PROBLEM TO BE SOLVED: To provide an underwater scale monitoring method for evaluating a scale adhesion state of an object river system in real time, accelerating a reaction to a result by using an electrical conductivity meter, and preventing an artificial mistake by further quantitatively evaluating the scale adhesion state of the object river system.SOLUTION: Predetermined voltage is applied between a pair of electrodes arranged underwater by being kept at predetermined distance, and scale adhesion of a river system is quantitatively evaluated by a current value flowing between the electrodes or a characteristic value corresponding to the current value. |
