1. A method of controlling a concentration or range of concentrations of a liquid or gas in an enclosure, the method comprising:
positioning an injection station within the enclosure, the injection station comprising:
a liquid or gas source;
a sprayer assembly; and
a delivery system that delivers the liquid or gas from the liquid or gas source to the sprayer assembly;
monitoring a concentration level of the liquid or gas in a local environment surrounding the injection station using a sensor located at a location outside of a housing of the injection station and exposed to the local environment to directly monitor the concentration level at the location outside of the housing and the sensor providing a signal indicative of the concentration level in the local environment to a controller; and
the controller controlling the flow of the liquid or gas to the sprayer assembly based on the signal.
