摘要
A method for testing the breath alcohol (ethanol) content with an embedded PC computer with a touch screen display uses software graphics with icons and graphs displaying an instant representation of the flow rate and breath alcohol concentration of the breath being delivered by the person taking the test. A software graphics using icons and graphs provides control panels by which a test administrator or technician is able to control fundamental operations and adjustments of the instrument. A geared, stepped, multiple optical component placement system having dual plates retains these components, and is capable of precision placement of all components using one electro-mechanical device. An infrared optical filter system operates between 3 and 10 microns. The results are stored in memory and are capable of comparisons to empirical tables for chemical identification.
