Abstract

A system and method is disclosed for indicating satisfactory times for titrating a chemical solution, e.g., cleaning product, used by a utility device to clean and/or sanitize various types of articles. The utility device is described in an exemplary embodiment as being a warewashing machine (100) that applies the chemical solution to articles provided to the machine on racks (104). The chemical solution is formed in a solution tank (140) from a combination of at least one chemical product and at least one rinse agent. Whereas the chemical product is described as a detergent, the rinse agent is described as water. Over a time period including multiple wash cycles, the chemical product and the rinse agent are added to the solution tank (140), thereby changing conductivity of the chemical solution. The present invention senses various types of information associated with the formation of the chemical solution and applies one or more test conditions to the sensed information to determine satisfactory time periods for measuring concentration of the chemical product relative to the chemical solution. Indications of the occurrence of these satisfactory times are presented on a display module (206) in a manner visible to field persons responsible for titrating the chemical solution.
