呼出气体酒精含量探测器检定的注意事项

Precautions During the Verification of the Detector for Alcoholic Quantity from Breathing-Out Gas

介绍呼出气体酒精含量探测器的工作原理和国家标准对使用探测器的要求,为确保探测器有效准确的量值溯源,采用呼出气体酒精含量探测器自动检测系统进行检定。该系统能够解决标准气体不易保存和定值容易发生改变的难题,同时控制吹气压力,保证探测器采样的一致性,并列举了检定操作时应注意的问题和细节。

The principle of breathing-out gas alcohol content detector and the national standard requirements to the detector were introduced. To ensure the detector effective accurate quantity traceability, the breathing-out gas alcohol content detector automatic detection system was used for test. This system could solve the problems such as the standard gas was not easy to preserve and the standard value was easy to change. The consistency of the detector sampling was guaranteed by controling air blowing pressure. At the same time, details and precautions in the test operation was listed.
