摘要： AN APPARATUS FOR THE DETERMINATION OF THE ALCOHOL CONTENT OF AN ALCOHOLIC LIQUID, ESPECIALLY ALCOHOLIC BEVERAGES OF THE FERMENTATION OR DISTILLATION TYPES. A SMALL KNOWN QUANTITY OF THE ALCOHOLIC BEVERAGE IS HEATED TO DISTILL THE ALCOHOL THEREOF INTO A PREDETERMINED QUANTITY OF A MINERAL OXIDIZING AGENT OF KNOWN CONCENTRATION AND PRESENT IN EXCESS. THE ALCOHOL IS CONVERTED TO ACETIC ACID AND THE UNREACTED OXIDIZING AGENT IS TITRATED WITH A REDUCING AGENT OF KNOWN NORMALITY, THE ENDPOINT BEING DETECTED BY MONITORING THE REDOX POTENTIAL. INCREMENTS OF ADDITION OF THE REDUCING AGENT ARE COUNTED WHEREBY THE ALCOHOL TITER IS READ OUT DIRECTLY UPON A COUNTER.
