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 that applies the chemical solution to articles provided to the
machine on racks. The chemical solution is formed in a solution tank 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, 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 in a manner visible
to field persons responsible for titrating the chemical solution.
