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

A method for recognizing sensor poisonings in portable gas-measuring devices with a test station having a main unit with a control and analysis unit and test modules connected with the main unit for data exchange with an connected device. The test station recognizes device model and/or gas sensor model of the connected device. The main unit has gas inlets for different test gases and there is a first gas feed line for sending test gas to the test modules and a second gas feed line for sending purging gas to the test modules and a gas drain line to return gas from the test modules to the main unit. The method includes detection of a first measured value and of a second measured value and determination of sensor poisoning on the basis of the two values. The test station control and analysis unit carries out the method.
