Abstract
A testing device for detecting vapor emission of at least one leakage point has at least one upstream measuring unit arranged upstream of the leakage point and at least one downstream measuring unit arranged downstream of the leakage point. The at least one upstream and the at least one downstream measuring units are connected serially. The at least one upstream measuring unit determines measured values of a reference stream and the at least one downstream measuring unit determines measured values of the reference stream plus a vapor emission of the leakage point. By comparing the measured values, the humidity quantity and thus the vapor emission at the leakage point can be determined.
