The following lists major application examples by measurement method. In this way, the output signal of the sensor is only related to the oxygen content in the sample gas, and has nothing to do with the total amount of gas passing through the sensor. Oxygen is a paramagnetic gas (a gas that can be attracted by a magnetic field is called a paramagnetic gas). 2. As long as the potential applied to the electrode is measured, the unique electrolytic potential of the measured gas can be determined, so that the meter has the ability to select and identify the gas to be measured. An Orsat gas analyser is a piece of laboratory equipment used to analyse a gas sample (typically fossil fuel flue gas) for its oxygen, carbon monoxide and carbon dioxide content. An oxygen sensor (or lambda sensor, where lambda refers to air–fuel equivalence ratio, usually denoted by λ) is an electronic device that measures the proportion of oxygen (O 2) in the gas or liquid being analysed..
