残留塩素計。 A sensor for measuring the available chlorine concentration in a liquid to be measured using a polarographic method, a salt water supply means for supplying a NaCl aqueous solution of a constant concentration at a constant flow rate, and a flow path through which the NaCl aqueous solution from the salt water supply means are flowed are provided. a chlorine generation flow cell in which a metal inert anode is provided in a flow path and a cathode is provided in an electrolyte chamber separated from the flow path through a diaphragm; a constant current generation source that flows a constant current between the electrodes of this chlorine generation flow cell; A flow path switching means that switches between a flow path on the side of the liquid to be measured and the side of the chlorine generation flow cell and connects it to the sensor, and a calculation control section that performs calculations on the detection signal from the sensor and generates various control signals. established,
At the time of calibration, a current is passed from the constant current source between the electrodes of the chlorine generation flow cell to generate a standard solution with a constant effective chlorine concentration, and this standard solution is applied to the sensor to perform span calibration. Residual chlorine meter.
