Abstract
The present invention provides an arrangement of equipment and an overall process for the measurement and control of active bleach concentration in a bleach environment of an industrial laundry or cleaning system. As a preferred embodiment the primary piece of equipment which renders the overall system especially useful in controlling, for example, hypochlorite ion in a bleach environment is a membrane-shielded amperometric probe. The probe is designed and membrane selected to be highly selective to fluctuations in hypochlorite ion concentration.
