A breath alcohol measurement device has a sample collector () with a sample inlet () configured for a contactless introduction of a breath sample. A measurement unit () has a sensor () that generates a measurement signal based on an alcohol content in the breath sample. A control and evaluation unit () determines the alcohol content based on the measurement signal and transmits a result-specific signal to an output unit (). Some of the breath sample provided into the sample inlet () is applied, at least intermittently via a main flow duct (), to the sensor () via a measurement gas duct () that is connected via an outlet to the environment (). Between the sample inlet () and the outlet of the main flow duct there is a further outflow opening () through which some of the breath sample introduced into the sample inlet exits into the environment.

Breath alcohol measurement with contactless sample collection

A gas routing element () for gassing at least one gas-measuring device (-), whereby each gas-measuring device (-) can be arranged in a test module (-) of a calibrating station (). The gas-measuring devices (-) have a first gas inlet opening (-), a communicating feed duct (-) and a communicating first gas outlet openings (--). Second gas inlet openings (--) are connected to a communicating recirculating duct (-) and a second gas outlet opening (-) is connected with the recirculating duct (-) in a gas-communicating manner. A fastening device () fastens the gas routing element () to the calibrating station () or to a test module (-) of the calibrating station (). A calibrating station () is also provided for the gas-measuring devices (-) with such a gas routing element ().

Calibrating station with external gas routing track

A test station for a plurality of test gases, includes a main unit () with a control () and test modules (), each for a gas measurement device, that exchange data to register a type of gas measurement device and test gas(es) required for the device type. The control sets a schedule for a test using a test gas, or for a plurality of successive tests each with different test gases and carries out the specific test planned according to the schedule, in parallel with tests for all of the test modules for a test gas and determines, as an additional gas measurement device is inserted, based on the particular device type of the additional gas measurement device, whether the currently-running test with the current test gas is suitable for the inserted test module; and if the test gas is suitable, to start the test for this test module.

Test station for portable gas measuring devices

The transmission of energy from the base station () to the mobile gas-measuring device () is carried out reliably and with a high level of safety, even in the presence of explosive gases with a gas-measuring system () including a mobile gas-measuring device () with a battery unit () and with at least one sensor () for detecting a gas concentration. A base station () for the mobile gas-measuring device () is provided as well as an interface () for transmitting electric energy from the base station () to the battery unit () of the mobile gas-measuring device (). The interface () for transmitting electric energy from the base station () to the battery unit () of the mobile gas-measuring device () is designed such that the electric energy is transmitted at least partly in a wireless manner.

Rechargeable gas-measuring system

Safety clothing () for persons in dangerous situations is provided including at least one device () for generating light and/or at least one device for generating sound and/or at least one mechanical device for generating a warning stimulus, which is perceptible by the person, an interface () for generating data or signals with a gas-measuring device () and a power supply device () for supplying the at least one device () and/or the interface with power. The features are in functional connection with one another, for optically and/or acoustically and/or mechanically warning the person when at least one limit value of a harmful gas is exceeded or in case of at least one implausible measured value of the air detected by the gas-measuring device ().
