3 Overview
Exhaled breath alcohol content detector (hereinafter referred to as wine detector) is used to detect the alcohol content in human exhaled breath
the amount. The wine detector consists of gas circuit, control circuit, alcohol sensor, breath detection system, sampling system and display printing system
And other components. According to the measurement principle, the wine detector can be divided into fuel cell type (ie electrochemical type), semiconductor type and infrared
Type and so on.
Among them, alcohol sensors, pressure sensors and temperature sensors are the key components and materials that affect the metering performance.
See Table 1.
