ABSTRACT:
Systems and methods include a test media, a reservoir containing fluid, and a sensor compared to measure a parameter that is related to an amount of fluid in the test media. Systems and methods may include a comparator to compare the parameter measurement to a parameter set point. Systems and methods may include a control system to control the addition of the fluid to the test media so that the parameter is maintained at a steady state value.
