1. , for carrying out a system for breath test to personnel, described system comprises:

  • Sensor unit (5), described sensor unit comprises;

    First sensor element (8), described first sensor element is configured to detect and is flowing through existence and/or the concentration of the volatile matter existed in the moving air of the breathing in pre-entry region (4), and produces the signal of the concentration corresponding to described volatile matter;

    Second sensor element (7), described second sensor element is configured to the existence of the tracer gas detected in described moving air;

    Analyzer (10), described analyzer is configured to the concentration of the described volatile matter measured in the breathing of described personnel, and described mensuration is the described signal based on the concentration corresponding to volatile matter;

    For generation of the mechanism (10,12,14) with the described air flowing of control, describedly include fan or pump (9) for generation of with the mechanism controlling the flowing of described air, describedly be suitable for after breathing being detected, interrupt the flowing of described air for generation of with the mechanism controlling the flowing of described air, wherein, the standard for breathing detection comprises trace gas detection.
