示出并描述了用于呼吸酒精测量装置（25）的校准装置（1）以及包括这种校准装置（1）和呼吸酒精测量装置（25）的系统。 在校准装置（1）中提供了一个测试气体容器（3），其将能够经由出口（5）流动到测量适配器（9）的入口（11）中的测试气体）提供。 测量适配器（9）形成流路（17），其中测试气体经受动态压力。 测量适配器（9）被配置为连接到呼吸酒精测量装置（25），当测试气体的动态压力达到呼吸酒精测量装置（25）的压力阈值时，触发测量。

Shown and described is a calibration device (1) for a breath alcohol measuring device (25) and a system of such a calibration device (1) and a breath alcohol measuring device (25). Here, a test gas (3) is in the calibration device (1), provides a test gas, which via an output (5) in an inlet (11) of a measurement adapter (9) can flow, wherein a measurement adapter (9) has a flow path ( 17), in which the test gas is subjected to a back pressure. The measuring adapter (9) is designed for connection to a breath alcohol measuring device (25) which triggers a measurement when the back pressure of the test gas a Druckschweliwert the breath alcohol measuring device is reached (25).
