1. A diluent preparation system comprising:
a concentrated reagent source supplying a concentrated reagent;
a water source supplying water;
a reservoir containing a mixture of the concentrated reagent and the water; and
a measurement system configured to detect a quality component of the mixture, the measurement system comprising
a sensor configured to detect the quality component, wherein the sensor is located in the reservoir, and
a calibrator configured to perform a calibration protocol comprising calibrating the sensor with a calibration liquid while the sensor is located in the reservoir, wherein the calibration protocol comprises rinsing the reservoir with the calibration liquid, draining the calibration liquid from the reservoir, and then calibrating the sensor with the calibration liquid.
