Claim 17:
18. A measurement device comprising:
a testing chamber comprising a gas inlet and a gas outlet and an internal volume for arranging at least one gas sensor,
wherein the measurement device is configured to:
perform a first measurement in which the at least one gas sensor is exposed in the testing chamber to a test gas under first gas conditions including a first pressure of the test gas;
perform a second measurement in which the at least one gas sensor is exposed in the testing chamber to the test gas under second gas conditions including a second pressure of the test gas, the second gas conditions being different from the first gas conditions,
wherein the second pressure is different from the first pressure, and
wherein the gas sensor is exposed to an intermediate pressure different from the first pressure between the first measurement and the second measurement; and
perform the first and second measurements in the testing chamber; and
during a time between the first and second measurements, remove the test gas of the first measurement from the testing chamber, wherein the gas sensor is exposed to a vacuum during the time between the first and second measurements; or

performing the first and second measurements in the testing chamber, wherein during the first measurement and the second measurement at least the outlet is closed.
