手持式乙醇测试仪的研制

Development of hand-held alcohol detector

介绍一种新型的乙醇测试仪的设计原理、实用电路及实验结果。该仪器具有体积小、灵敏度高、选择性好、稳定性高、响应时间短、手持、能方便地现场实时地检测气体中气态酒精浓度等特点。可用于交通安检及酒厂、食品工厂发酵的监测。

The designing theory, practical circuit and experimental result of a new-type alcohol detector are reported. The detector has the features of small size, high sensibility, good selectivity, high stability, short response, being hand-held and the convenience to give an on-the-spot and real-time detection of the concentration of gaseous alcohol in gases. It is applied to safety inspection in transportation and fermentation monitering in breweries and food products factories.
