Spectrophotometric sensors for measuring the concentration of various solutions are disclosed. Methods for controlling the introduction of disinfectants using such sensors for water treatment are also disclosed. Hypochlorite strength is monitored in at least some embodiments.

主权项

1. A spectrophotometric hypochlorite sensor, comprising:
a first source of monochromatic radiation configured to produce an emitted light; a sample chamber configured and positioned to receive the emitted light and contain a sample comprising hypochlorite through which the emitted light passes to produce a partially absorbed light; a detector configured and positioned to receive the partially absorbed light and generate an input signal in response to receiving the partially absorbed light; and a processor configured to receive the input signal from the detector, correlate the input signal to a hypochlorite concentration of the sample, and generate an output signal indicative of the hypochlorite concentration of the sample.
