Abstract
A method for testing a gas sensor and a gas-measuring device with a testing device for testing the gas sensor provides an improved analysis and evaluation of states of gas sensors. Due to a testing of a gas admission element, by monitoring measuring signals (, () in a time course () in conjunction with dispensing () a quantity of test substance, it is made possible to check whether a gas supply to the gas sensor is possible (to check if the gas diffusion path is open) and given.
