段とを具備することを特徴とする残留塩素計。 A voltage applying means for applying an applied voltage to a diffusion current flowing between a rotating electrode immersed in a test liquid and a counter electrode, and a conductivity signal from a conductivity sensor immersed in the test liquid is inputted and predetermined. Voltage setting means for setting the applied voltage so that the fixed value of the applied voltage and the compensation rate are located at the center of the plateau of the group of applied voltage versus conductivity curves, and a correction concentration table corresponding to the PH value and the diffusion current value. a residual chlorine meter, comprising a correction calculation means which receives a PH signal from a PH sensor immersed in the test liquid and the diffusion current and corrects the concentration using the correction concentration table. .
