Abstract

This meter employs the thermocatalytic sensing method stipulated in Japanese industrial standards (jis M 7626). The drinking experiment was performed to prove the efficiency of the new alcohol meter model am-481. Ethanol concentrations in breath were determined by gas chromatography and alcohol meter and both readings were compared. By a study of breath ethanol concentrations, the following conclusions were drawn as for the alcohol meter. The alcohol meter has practical merits to determine breath ethanol. It is small, usable anywhere, fairly accurate, and can record the breath ethanol concentration determined and preserve the record. On principle, tobacco, thinner and breath of a diabetic may affect the determination by alcohol meter, but in reality such effects can be excluded by making the subject rinse his throat. As the determination values by alcohol meter and gas chromatography were compared, with the reading of the alcohol meter as y and that of the gas chromatograph as x, the following equation y = 0.942X + 0.001 (gamma = 0.996, p << 0.001) was obtained. It is concluded that the alcohol meter is practically and functionally excellent. (TRRL)
