A system and method is disclosed for controlling chemical dispense operations based on a conductivity offset determined for a chemical solution. The chemical dispense operations are performed by or in conjunction with operation of a utility device, such as a warewashing machine. The chemical solution is formed in a solution tank device by combining water with at least one component chemical product. The conductivity offset, which is the conductivity of the water, is used to normalize the conductivity estimated for the chemical solution relative to the component chemical product in the solution. During various points in time during operation of the utility device, the normalized conductivity is compared to a conductivity setpoint, and if the normalized conductivity falls below the conductivity setpoint, a specified volume of the component chemical product is supplied to the solution tank.
