ABSTRACT:
The present invention provides a sensor system for determining a concentration of a chemical component in a fluid having a first sensor that senses a first physico-chemical property of the chemical component and, a second sensor that senses a second, different physico-chemical property of the chemical component. A method to detect, control, monitor, maintain and confirm concentration levels of a decontaminant throughout a decontamination cycle is also provided.
