The Basics of an Oxygen Analyzer
If you are a scuba diver, you know the importance of using an oxygen analyzer. These handy electronic devices can quickly and accurately measure the amount of dissolved oxygen in your tank. In addition, these units can also help you monitor the level of gas in your cylinders and other tanks. Undetected leakage from these containers can be dangerous, so it is important to keep an eye on the levels of these gases.
Most oxygen analyzer scuba are designed for easy use, and you can find several models that are suitable for both recreational and technical scuba divers. These devices run on batteries, and they are usually equipped with a simple digital display that shows the amount of oxygen in a tank. Most oxygen analyzers can be calibrated for different types of nitrox mixtures, and some of them are even capable of measuring trimix blends.
Monitoring Oxygen Levels in Headspaces: The Role of Oxygen Headspace Analyzers
The basic type of oxygen analyzer uses an electrochemical galvanic fuel cell sensor to measure the amount of dissolved oxygen in a tank. These sensors are used in a wide range of applications, from checking the oxygen content of welding gas to ensuring that the air in scuba tanks contains the right level of oxygen for diving.
Other types of oxygen analyzers use more sophisticated methods to detect the presence of oxygen. Paramagnetic oxygen analyzers, for example, rely on the fact that dissolved oxygen molecules have a magnetic sensitivity. These sensors contain nitrogen-filled spheres suspended within a magnetic field, and the movement of these spheres is proportional to the oxygen concentration in the area.
