The system further includes a controller that is able to control the customization of the supply gas and the location of the common vessel portion.
Claims17
An open gas exchange measuring system including:
- a controller;
- a test chamber including a movable upper portion that selectively engages a first lower portion wherein a motor is coupled to the upper portion such that the upper portion is movable between the first lower portion and a second lower portion;
- a customizable gas source that provides gas to the test chamber, the gas source being controlled by the controller, the controller providing for customizing characteristics of the gas provided to the test chamber;
- and
- a gas measuring device.
