2007-8-1In order to inject the gas easily the chamber is evacuated slightly (≈ 1.133 × 10 − 1 mbar) using a rotary pump. After injecting the test gas, all the valves are closed to avoid the test gas leakage during the experiment. Then the resistance of the sensor is measured by changing the sensor temperature in air and in the injected gas ambient.
