Abstract
This invention is directed to a device which measures the oxygen component of a beverage gas using a specific oxygen probe, ultrasonic degassing, a special valving technique, and microprocessor based software. The measurement is made in the gaseous state in a two chamber system. The device is controlled by an electronic console that is built around a microprocessor which sequences and times the valves, receives the data from the oxygen probe and its accompanying temperature compensation circuit, and displays the data. An alternative method is to use several chambers and one pass. Additional chambers may be used to increase the speed of the test, control interferences, or aid in identifying gases other than the oxygen component. The device may also have an interface piercing head manifold that allows CO.sub.2 and oxygen to be tested in the same container and in one preparation. The invention also relates to specific gas measurements with non-specific type measurements and the general techniques can be applied to environmental problems that involve oxygen demand and respiration of bacteria.
