Human breath tester for quantitatively measuring alcoholic content as an indication of the state of intoxication, if any, of any person, typically an automobile driver. The unit is fully transistorized and is programmed to sequence through a purge and blank cycle prior to an actual test to assure a reliable reading. A digital display and printer provide duplicate output readings and a novel sample chamber construction insures accurately metered samples of deep lung breath. |
