Abstract
A residual chlorine meter for measuring the concentration of residual chlorine in sample water includes an indicator electrode and a counter electrode to be immersed in the sample water and a controller that measures the concentration of residual chlorine in the sample water based on a diffusion current flowing between the indicator electrode and the counter electrode in a case in which a voltage is applied between the indicator electrode and the counter electrode. The controller detects a degree of deterioration of a replaceable component of the residual chlorine meter based on a motor current, flowing through a motor that rotates the indicator electrode in the sample water, and/or the diffusion current.
