Development of a Breath Alcohol Tester with Temperature Compensation

Abstract

The purpose of this research is to develop and to find the quality and the efficiency of the breath alcohol tester with temperature compensation. The samples of the study were 20 peoples from the commuters who have already alcohol checked from the police, and the customers at the restaurant and the catering. The tools are the breath alcohol tester with temperature compensation which the researcher has developed and the imported alcohol breathe tester, SD-400, quality evaluation form and efficiency evaluation. The statistics used for data analysis were mean ( ) and standard deviation (S.D.). The result of this research shows that the quality of the breath alcohol tester with temperature compensation via using linear equation (= 4.36, S.D. = 0.50). This is at a good level. Also, it has equal standard value from the Department of Medical Sciences. However, the efficiency of the breath alcohol tester with temperature compensation compared with the SD-400 testing measurement has error not more than ±1.5 milligram percent (mg%) which is as well as the specified hypothesis.
