Abstract
A calibrating device () for a breath alcohol measuring device () as well as a system including such a calibrating device () and a breath alcohol measuring device () are shown and described. A test gas container (), which provides a test gas, which can flow via an outlet () into an inlet () of a measuring adapter (), is provided in the calibrating device (). A measuring adapter () forms a flow path (), in which the test gas is subjected to a dynamic pressure. The measuring adapter () is configured for being connected to a breath alcohol measuring device (), which triggers a measurement when the dynamic pressure of the test gas reaches a pressure threshold value of the breath alcohol measuring device ().
