Abstract
A purified water manufacturing device monitoring system includes: a detecting device that illuminates, with an inspection beam, water either that is in a process of being manufactured or that has been manufactured by a purified water manufacturing device, detects light in a region illuminated by the inspection beam, and detects a microorganism or a non-microorganism particle included in the water; a measured value specifying portion that specifies a measured value for a number of microorganisms detected and specifies a measured value for a number of non-microorganism particles detected; and a state evaluating portion that evaluates that a problem has occurred in the purified water manufacturing device when either or both the measured value for the number of microorganisms and the measured value for the number of non-microorganism particles are greater than a prescribed value.
