Test station for portable gas measuring devices

A test station for portable gas measuring devices for a plurality of test gases, the test station comprising:

• a main unit comprising a control and analysis unit and a plurality of gas inlets, each of the inlets for one of different test gases;
• a gas line;
• and
• a plurality of test modules, each of the test modules being connected to the main unit) and exchanging data with the main unit, into each of which a gas measuring device can be inserted for testing, detecting a type of gas measuring device that has been inserted into the test module and determining therefrom a test gas or test gases required for the detected type of device, whereby, under the control of the control and analysis unit, the test gas is conducted by means of the gas line to the test modules from a selected gas inlet, wherein the control and analysis unit is configured to set a schedule for a test with a test gas or a plurality of successive tests to be carried out each with different test gases in accordance with the device types currently determined in the test modules, and then to carry out each test planned according to the schedule with the associated test gas in parallel with the test for all test modules, for which the current test gas is suitable in accordance with the type of gas measuring device that has been inserted, and to determine, as soon as another gas measuring device is inserted into the test module and is reported as being ready for testing, in accordance with the respective type of the other gas measuring device, whether the currently running test with the current test gas is suitable for the inserted gas measuring device, and if the test gas is suitable, to start the test for this another test module.
