ABSTRACT:
An electrical system for automatically measuring, computing and indicating the oxygen content in a sample of fluid, using a galvanic cell that absorbs and consumes the oxygen from the sample, produces controlled current pulses of given duration that are conducted by the cell as necessary to maintain the cell voltage constant and these pulses are counted during controlled intervals and the count is displayed as a representation of the oxygen content of the sample.
