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 that has a metal inert cathode on the upstream side of the flow path and a metal inert anode on the downstream side, a constant current source that flows a constant current between the electrodes of this chlorine generation flow cell, and a device to be measured. A flow path switching means that switches between a liquid side flow path and the chlorine generation flow cell side and connects to the sensor, and a calculation control section that performs calculations on the detection signal from the sensor and generates various control signals, 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.
