摘要：PROBLEM TO BE SOLVED: To provide a passive solid-state residual chlorine sensor having a simple structure, and a water meter having the same.SOLUTION: A solid-state residual chlorine sensor 10 comprises a first electrode 11, a second electrode 12, and a voltmeter 13 connected to the first electrode 11 and the second electrode 12. A metal constituting the first electrode 11 is more responsive to free residual chlorine in tap water than a metal constituting the second electrode 12. Electrode potential of the metal constituting the first electrode 11 and that of the metal constituting the second electrode 12 vary similarly with variation of water quality factors of the tap water and environmental factors.SELECTED DRAWING: Figure 1
