1. A system comprising:
- a test media;
a reservoir containing a fluid;
a conduit between the reservoir and the test media, wherein the conduit is configured to supply the fluid from the reservoir to the test media;
a sensor configured to measure a parameter and obtain a parameter measurement, wherein the parameter is related to an amount of the fluid in the test media; and
a comparator configured to compare the parameter measurement to a parameter set point.

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.

12. A system comprising:
-
a test media comprising a quantity of a fluid;
a support system configured to support the test media and configured to transfer the fluid from the test media to the support system;
a fluid addition system comprising a control system and a supply of the fluid; and
a sensor configured to measure a parameter of the test media, wherein;
the parameter is related to the quantity of the fluid;
the fluid addition system is configured to add the fluid from the supply to the test media at a fluid addition rate; and
the control system is configured to control the fluid addition rate so that the parameter is maintained at a steady-state value. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21, 22, 23)

24. A method of measuring a moisture vapor transfer rate, the method comprising:
-
providing a test media comprising a quantity of moisture;
transferring moisture from the test media at a moisture transfer rate;
measuring a parameter with a sensor to obtain a parameter measurement, wherein the parameter is related to the quantity of moisture comprised by the test media;
adding a fluid to the test media at a flow rate; and
controlling the flow rate so that the flow rate is generally equivalent to the moisture transfer rate. - View Dependent Claims (25, 26, 27, 28, 29)
