Can Oxygen Gas Detectors Read Nitrogen Concentration?
No. Oxygen gas detectors are designed to detect oxygen concentration, not nitrogen. If you want to detect oxygen and nitrogen at the same time, then you can choose the all-in-one gas detector, the common all-in-one gas detector on the market is able to detect 6 gases at the same time, but you need to configure the type of gas to be detected at the time of purchase. Here's a look at the principle and application of oxygen detector and nitrogen detector.
The reason why the gas detector can detect gas, because the detector has a part called gas sensor, this sensor needs to be detected according to the type of gas, detection accuracy and range as well as the use of the environment and other conditions of choice, can be simply understood as a selection of customized, so the oxygen gas detector can not detect nitrogen.
Common oxygen sensor principle of electrochemical, optical, zirconium oxide and paramagnetic oxygen and other types. Electrochemical sensor is the most common one, the use of oxygen will react with the sensor and produce an electrical signal proportional to the gas concentration, the sensor consists of two electrodes. This type of sensor can choose from a wide range of conventional detection range, there are also high-precision high range. Optical oxygen sensors utilize the principle of fluorescence bursting, and by using a known light source, the detected light energy is inversely proportional to the number of oxygen molecules in the sample gas. Fluorescent oxygen sensors have a longer life and are less susceptible to interference from other gases than conventional electrochemical sensors, but are available in smaller ranges. Zirconia oxygen sensors are similar to the electrochemical type, utilizing a zirconia surface covered with a layer of platinum to form a concentration cell, which has a wide range of applicability and low interference, and can be used to analyze the oxygen content of flue gas. Paramagnetic oxygen is designed according to the oxygen has high magnetism, the magnetization rate of oxygen is much higher than other gases (such as nitrogen, helium, argon, etc.), and is insensitive to mechanical shock, more stable, but easy to cross-sensitive to other gases.
